For Damaged and Thinning Hair Types

Expertly handcrafted with a hydrolyzed keratin boost, silk peptide proteins, and pasture-raised grass-fed bovine hide collagen peptides.

Experience true food for your hair and skin with real, nutrient-dense, traditionally handcrafted soap made with old-fashioned ingredients. Our artisanal shampoo soaps are handmade with carefully curated local, grass-fed, pasture-raised, and organic ingredients – proudly sourced from small family farms and homegrown here in the USA. What we can’t source locally, we seek the highest quality: certified organic, minimally processed, and fair-trade ingredients to feed your hair and skin from the outside-in. No detergents or surfactants are used in any of our shampoos.
When washing properly, our basic unscented formula is suitable for all hair types used as-needed with an optional conditioner. Some scents and additional ingredients on top of our basic formula may alter results for each individual.

Top 3 Tips for Beginners:

  1. Please keep in mind that scent information in this product’s scent tab is based on majority feedback.
  2. Beginners, we recommend trying our unscented shampoo soaps first for the freshest, cleanest, and most simple start. Beginners will also want to educate themselves on the possibility of a short detox period and the correct washing technique.
  3. Our All-In-One Shampoo – Body – Shaving soap bars are also suitable for regular body washing, face washing (facial soap directions here), and shaving (shaving directions here). Our ingredients are LOW on the comedogenic scale – so your pores are nourished and cleansed, but never clogged.

Ingredient Details (read full ingredients list in this product’s ingredients tab)

Keratin

Keratin is a building-block of hair, skin, and nails. Our hydrolyzed keratin is in a gentle and more bioavailable form – highly contrasted with salon “keratin treatments”, that is NOT what this shampoo soap is! Rather than causing irreversible damage with chemical infusion, our hydrolyzed keratin feeds the hair at the root and outer layer. Keratin smooths cells that overlap to form hair strands, which means more manageable hair and less frizz. This makes for hair that dries with little frizz and has a more glossy, healthy look to it. Keratin can also reduce the look of split ends by temporarily bonding the hair back together.

 

Silk

Silk protein peptides strengthen and yet smooth hair bonds: silk is one of the strongest (yet softest) substances in the world and is a perfect addition to your haircare routine. Our real, natural silk comes from cruelty-free silk moth cocoons: the cocoons are harvested after the moths mature and leave the empty cocoon behind.

 

Collagen

Our pasture-raised and grass-fed bovine collagen is another vital building compound for healthy hair, skin, and nails. Our collagen is hydrolyzed, making it more bioavailable for the hair to deeply utilize. Collagen helps moisture penetrate the hair shaft, locking it in for long-lasting shine and flexibility.  Another serious boost to consider: collagen may help reduce the appearance of gray hair by supporting the healthy structure of the hair follicle (where the pigment that gives hair its color is produced). Therefore, collagen is basically an anti-aging nutrient for your hair, bringing back healthy shine, bounce, and structure.

 

Lard

Pasture-Raised, Pure, Hand-Rendered USA Lard feeds your hair and skin extra-nourishing balanced fatty acids and the world’s highest Vitamin D3 content, second only to cod liver oil. Lard has been used in haircare since medieval times for hair growth and hair health management. Our lard is carefully hand-rendered to keep its precious rare nutrients in-tact.
Lard is the 2nd fat in the world that is highest in Vitamin D3, second only to cod liver oil! Vitamin D3 is the most bioavailable form of Vitamin D. Vitamin D delivers a myriad of health benefits, including supporting healthy, long hair. As it turns out, Vitamin D3 is involved in various signaling pathways in the hair follicle and has a direct (and critical) role in the hair growth (aka anagen) phase. Topical application of vitamin D3 has been shown to render protection against damage caused to the skin by UV light. Vitamin D reduces cell death, promotes cell survival, and reduces redness and inflammation.
Since pasture-raised lard is lighter and softer in texture, slightly higher in unsaturated fatty acids, and higher in certain nutrients like Vitamin D3 – it makes a perfect fat base in our shampoo soaps, conditioners, and hair oils.
Pasture-Raised, properly fed lard is low on the comedogenic scale: it will not clog pores nor cause inflammation, in fact it may help with those issues. Since it is slightly higher in unsaturated fatty acids, it provides a more bubbly lather and a squeakier clean.
Our Lard is:
  • Slowly and carefully hand-rendered in our facility from the farm-fresh raw source
  • NEVER bleached or ultra-processed for a “white look”
  • Pasture-Raised from LOCAL and USA small family farms

Buttermilk

Local, Raw, Farm-Fresh, Grass-fed, Hand-Cultured Buttermilk to feed your hair the perfect food – high in essential vitamins, minerals, proteins, and fatty acids. Full-fat Jersey cow buttermilk is higher than goat milk in lactic acid and has the same moisturization content. The famously beautiful Egyptian Queen Cleopatra was a wise proponent, bathing in fresh buttermilk daily.
Buttermilk is high in multiple different proteins, vitamins, and minerals. Farm-fresh, raw buttermilk can have dozens of naturally occurring probiotics along with alpha-hydroxy acids like lactic acid, which promote cell renewal and rejuvenation of beauty factors such as brightness, tone, and complexion maintenance. Milk is considered a “complete protein” and “near-perfect food” meaning it contains all nine of the essential amino acids necessary for your body to function at an optimal level, plus all the essential Omega 3, 6, & 9 fatty acids in balanced proportions in addition to most of the vitamins and minerals your body needs. And buttermilk is even better! If raw milk can grow a baby calf into a cow within a few months, think of what it does to your hair!
Our Buttermilk is:
  • Slowly and carefully hand-cultured from the farm-fresh raw source
  • When the farm-fresh raw buttermilk arrives in our facility, it is frozen and used first-in, first-out to ensure the best nutrient content
  • Grass-Fed and Pasture-Raised from LOCAL small family farms

Babassu Oil

Certified Organic Babassu Oil provides an extra foamy lather to build mounds of thick bubbles. This makes cleansing your hair an easier task without using pore-clogging palm or coconut oils. Babassu oil also helps maintain the hardness of your shampoo soap while in use and makes the bar last as long as possible in wet environments.

 

Olive Oil

Certified Organic, Cold-Pressed, Extra-Virgin Olive Oil has been used for thousands of years to make the best soaps in the world and is one of the major components of our shampoo bars. Olive oil provides a rich, smooth, silky shine to hair shafts while also retaining a mild, gentle cleanse. Olive oil is unique in that it’s very moisturizing, but not heavy.

 

Castor Oil

Certified Organic, Hexane-Free Castor Oil has been used for centuries to help heal damaged skin while also restoring new hair growth.* Also known as the “Palm of Christ”, its many priceless uses have yet to be overshadowed by any other known oil. Castor oil also helps to provide a thick, robust, and stable lather, while additionally strengthening the hair shafts and reducing split ends.

 

Jojoba Oil

Certified Organic Golden Jojoba Oil is actually a type of liquid plant wax that is claimed to be very similar to our skin’s sebum, providing a light moisturization without clogging pores. Jojoba oil has been very useful for haircare professionals, lending extra shine, strength, and manageability to hair health.

 

Abyssinian Oil

Abyssinian Oil is very similar to Argan oil but shown to be better in some ways. From multiple scientific studies, Abyssinian oil has been shown to provide superior protection against hair breakage and heat damage in professional salon settings. Shine and manageability are also markedly improved when incorporating Abyssinian oil into one’s haircare routine.

 

Kaolin Clay

Kaolin Clay helps detox your hair from the daily grime and air pollution from modern day living while also soothing and nourishing the scalp with trace minerals. This natural earthen clay assists with dandruff and encourages hair growth as well. For shaving, it lends an extra silky-smooth experience, but if a nick does occur – it helps stop and repair bleeding quickly. Just lather our soap on the area you need to shave and shave as you would normally (full shaving directions here).

 

Fragrance Oils

Phthalate-Free and Paraben-Free Fragrance Oils are included for a familiar and comforting scent. Did you know that most body care shoppers make their purchase decisions based solely on scent satisfaction? The olfactory system is directly related to emotions and memories, which is why scents are such an important factor for many. Please keep in mind that not including phthalates and parabens will reduce the scent hold, decreasing the linger time and strength compared to what many are used to with store-bought products. Learn more about our safer fragrance oils HERE and read about this product’s scent and scent strength in the product’s scent tab.

  • Hair Growth – Our shampoo bars tend to cause faster and thicker hair growth. As a side-effect, more frequent root colorings/treatments may be needed for colored/treated hair.
  • Colored & Treated Hair – Our shampoo bars tend to have no effect on the shade of permanently colored hair or texture treatments. However, semi or demi-permanent hair-colorings or texture treatments can wash out faster due to the vigorous washing method required for a natural shampoo soap lather. We ask you to weigh your priority of healthier, thicker and faster-growing hair with your semi-permanent hair treatments. Please consider a more permanent hair color shade if you do need to color your hair.
  • More Curly/Textured Hair – Our shampoo bars are sulfate-free and totally natural, therefore they will strengthen the natural disulfide bonds in your hair, which will bring out your natural hair texture. Your natural hair texture usually has more volume, curl/texture, and definition than what you were getting with detergent or surfactant shampoo products.
  • It often takes more time and effort to use natural shampoo bars, but it’s well worth it in the end. Not only do you end up with more naturally nourished hair, you also end up with a cleaner environment!

On average, 1 shampoo soap will last most experienced users around 2 weeks of daily use, or about 14 hair washes on average.

Hair length, thickness, texture, and level of oil/grease/dirt to cleanse will affect this number. The longer, thicker, dirtier, and more textured your hair is, the more you will need to apply for a good wash. Another factor that will affect duration is if one is using the bar for more than just hair washing: for example, as a body soap and as a shaving soap in addition to a shampoo.
When you first start using shampoo soaps you will go through them a lot faster than after you adjust – this is due to the detox/adjustment period for most beginners. Here is an article about this if you are interested: https://perma-earth.com/shampoo-soap-detox-for-beginners/
Another beginner’s adjustment is not properly washing (not applying and lathering enough), which causes soap residue in certain places and feels much like the detox symptoms. Here is our article about how to wash properly: https://perma-earth.com/directions/soap-directions/

  1. Haley Lawrence

    Okay so this soap, I originally got in a conditioner small sample size. The minute I smelled it, it brought me back to something SO pleasant in my teenage years. It is truly a very delicious smelling and pleasant smell. I wouldn’t even hesitate to give this scent a try. You will NOT be disappointed.

  2. Naomi Swanson

    This is the bar I’m currently using right now and I couldn’t be happier. My hair comes out so soft and clean. I have a really hard time finding a good shampoo because I have an easily irritated scalp but these natural ingredients cause 0 problems. The scent is warm and subtle and stays until the next wash. Absolutely will be buying from them again.

  3. kayteelizabthx

    Very nourishing shampoo. Certainly leaves hair feeling soft and silky, without leaving it greasy or weighing down thin hair. Repaired and revived my damaged hair, as advertised.

  4. whatsinbooks

    I have curly hair that for well over a decade has been weighed down by tons of product. I was always buying new shampoos and styling products that promised to enhance my curls with no luck. I stopped wearing my hair curly because I was so frustrated about how frizzy, messy, undefined, and unpredictable my curls looked. I tried a natural tallow shampoo bar from a different company a few months ago and loved the way it made my hair look and feel after the detox period. I have since been using Perma Earth’s shampoo bars and I love them even more than the other company’s shampoo bar. This keratin bar is wonderful- it has brought my curls back to life with no effort or extra product needed! I wish I had tried these bars years ago! APPROVED

  5. Karin Pinheiro

    I’ve been trying all natural shampoos forever. Lush being one that worked well but I wanted to move away from that brand and found Perma Earth! The washing instructions for the shampoo make a world of difference and after 3 days I had the softest, best smelling hair ever!! My husband noticed how awesome my hair looked and noted it even looked more radiant and made my dark brown hair look richer in color. I’m hooked. And the scent. I cant even describe. Floral yet..something else. For reference I have thick, course, wavy hair. Its hard to find shampoo that doesnt weigh it down, while accentuating the waves and making it soft.

  6. TS

    I’m in my mid-50s, naturally blonde, but have been going gray for years, probably 70% or more gray now, decided this last hair salon visit to stop coloring my hair and see how it goes (my stylist has been encouraging me to do so as well based on the color of my gray). I also have fine hair, but a lot of it, wavy/curly and prone to frizz, which drives me nuts trying so many products to combat it. I’ve been using P-E shampoo/conditioner bars for a few months now and really liking them, plus no chemicals, and I also use the leave-in conditioner. I just started using this Coco Cashmere bar with a conditioner bar and noticing a difference in my hair after just 2 washings (I only wash my hair 2-3 times a week), hair is softer and less frizz, first time I blow dried it, second time was air dried, the latter one was a more noticeable difference with less frizz even the next day. I think the shampoo bars marked as “Repair & Revive” with added keratin, silk, collagen are the right formula for my hair, plus they don’t weight my hair down either, and will be buying more of these.

  7. amyscorby

    I just started using this 5 days ago and while my hair is detoxing I can feel the difference. Plus it smells so good.

  8. Courtney Robles

    Very awesome scent! Cleanses skin and hair nicely. As long as I don’t forget the bars at home when I go out of town my hair continues to wash so well but if at anytime I use conventional shampoos and conditioners my hair has to go through a few washings with the bars to make it feel squeaky clean again and softer.

  9. Elyse Seibert

    This is my second shampoo bar I’ve tried, and it’s going to be tough to top it! My hair looks so vibrant and bouncy. I can go longer between washes because of how well this bar cleans. I’m so glad I found Perma Earth, and I will definitely be recommending this shampoo bar to my friends and family.

  10. stephanie.chica.scott

    This was the first shampoo bar I tried and I’ve been hooked ever since. I have decently long hair that is wavy/loose curls. A lot of products I have tried in the past weigh my hair down but this shampoo bar made my hair so bouncy and voluminous while still defining my curls. I also love this scent it is definitely one of my go to for fall/winter. I was describe it as warm and sensual. I am sensitive to fragrances and I had no issues with this at all. The scent isn’t too over powering but enough to linger on your hair throughout the day. I would 100% purchase again.

  11. Kristi Rieder

    This is my favorite shampoo bar so far! I’ve just finally got past the detox phase of my hair and couldn’t be happier. I tried a natural shampoo routine a few years ago with homemade products but it just didn’t work out. I was looking to get back into trying something natural and this definitely fits the bill. I’m trying to stick with one bar for a while but there are so many I want to try… If you are looking for moisture and shine without feeling to heavy…this one is where it’s at! Love all the products I’ve tried so far 🙂

  12. Ariana Cannell

    I wasn’t sure I was going to like this bar because chocolate scented products don’t usually do it for me. BUT I really like this bar. The Cocoa scent is not artificial smelling and is subtle and fades throughout the day. The Cashmere part is no lie. It feels silky in your hand and my hair felt soft and silky too. This would probably be a good one for the men in your life as well. @arianacannell

    • natalie buchwald

      I have fine hair but I have a lot of it. It’s also curly. Before I discovered these shampoo bars (and the conditioners) my hair would always be frizzy after washing and I always had to do something to prevent that from happening. Since using these shampoo bars I am now able to just leave my hair alone after washing and it dries beautifully in these gorgeous ringlets. I new these bars would be a healthier option than the (so called) high quality stuff I used in the past (Aveda, DevaCurl, Ouidad, etc) but I never expected such an amazing result. PLUS this Cocoa & Cashmere smells divine. Thank you Perma Earth, God bless you guys!
