Keratin hair mask is an indispensable product for those who want to restore and improve the condition of their hair. After using the mask, the hair looks more well-groomed, shiny and healthy. **Pros:** 1. **Restoration**: The mask penetrates deep into the hair structure, filling damaged areas and making them stronger. 2. **Moisturizing**: It provides intensive hydration, which is especially important for dry and damaged hair. 3. **Simplifying styling**: After using the mask, the hair becomes more manageable, easier to comb and style. 4. **Long-lasting effect**: With regular use, a long-lasting effect is noticeable, the hair looks healthier and more well-groomed. **Cons:** 1. **Price**: High-quality keratin masks can be quite expensive. 2. **Product Sensitivity**: Some people may be allergic to certain ingredients, so it is important to check the ingredients. 3. **Not for all hair types**: For fine hair, the mask may be too heavy, making it more oily. Overall, a keratin mask is a great choice for restoring and caring for your hair, especially if you have damaged or curly locks. It is recommended to use it regularly for maximum effect.

used it immediately while the order has been delivered. It has a unique colourless formula. It make my hair and scalps moisturized with good soft scent. I will buy it again because of its high quality, great packaging and a very great composition as it contains keratin, shea butter and coconut oil with all of them benefits, good size and price.

Not for me

This had such great reviews, but it's not doing much for my hair, I prefer natural masks out there that are actually more hydrating

I am so happy with this Keratin hair mask. After just one use, my hair felt incredibly smooth and silky. It really helps tame frizz and makes my hair much easier to brush through. The 12 oz jar is a great size and a little goes a long way. If you have dry or unruly hair, this is a must-try for getting that sleek look!

Nice smell and texture

Good value jar, I use these on the day I wash my hair and leave it in for some hours. Can notice that my hair feels much softer afterwards. Have noticed improvements in my hair quality but could not say if this mask is the (sole) contributor to that as I made some other changes too. Will repurchase.

My Experience with Advanced Clinicals Keratin Hair Mask

I’ve been using this mask for a little while now, and honestly, it surprised me in a good way. The first time I used it, my hair felt instantly softer and way smoother. I have hair that gets frizzy and dry easily, especially at the ends, and this mask made it feel more “put together” and moisturized without making it greasy. The texture is thick and creamy, which I like because it spreads easily and you don’t need too much. The smell is strong at first, but it’s nice and leaves my hair smelling clean and fresh even the next day. After a few uses, I noticed my hair looking shinier and less puffy. It feels stronger too, like it has more weight and smoothness. It doesn’t fix split ends or anything dramatic, but it definitely makes the hair look healthier.

Amazing Keratin Hair Repair

I am absolutely thrilled with this Keratin Hair Mask!The quality is incredible, especially considering the price point. I have seen a huge benefit in the sleekness and smoothness of my hair after just a few uses. The composition is rich with keratin, which helps repair damage regardless of age. The mask has a pleasant scent that isn't too strong. The large 12 oz size of the package means it will last a long time, which is great for frequent use. It's now a vital step in my hair care routine.
