As L’Oreal pro-keratin is the only one hair mask I own (yes, it is true!) I thought I could cover some science behind. The packing says it is pro-keratin refill, which means restoring hair, probably damaged, dry and porous hair. Ingredients that excite me are cetearyl alcohol, which is moisturises hair and it is pretty common in hair products.
Amino acids, such as arginine, glutamic acid and serine are great as they are essential to maintain the strength of the hair. However, I am not too keen for mineral oil as it does have mixed reviews. I found research article comparing mineral oil against coconut oil and certainly coconut oil is much better for hair. Mineral oil can also leave hair feeling more heavy, which for people with curly hair might be an issue. Also, parabens come to my attention as a lot of consumers are trying to avoid them. My opinion – they are not bad as they prevent bad bacteria growth. As always you will find a bit of fragrance , which is standard in hair products.
My hair is in a good condition and after using it it did feel soft but I did not notice much of a change. If you bleached your hair or it is very dry this might do a trick for you!
Have you tried this product before? Any other hair masks I should be aware of? Let me know!
