    I stumbled upon the K18 Peptide Prep pH Maintenance Shampoo and decided to give it a shot, and boy, am I glad I did! It’s like a breath of fresh air for my hair. Not only does it cleanse thoroughly, but it also leaves my hair feeling soft and manageable. I’ve noticed a difference in the overall health of my hair since using it – less frizz, more shine, and fewer tangles. Definitely my new go-to shampoo

    One of the shampoos that was found in HairUP was this pH balancing shampoo and I was delighted to give it a try. My hair type is problematic in that it is oily at the scalp and dry towards the ends which causes frizzing and hair breakage. Having treated my hair with the K18 shampoo only twice a week for a month, it is possible for me to note that the appearance of the hair has improved noticeably. In addition, the formula is mild but efficient in decreasing the deposits’ thickness without overdrying. The hairs appear shinier and they do not frizz when I comb them as much as before. I can definitely say that if you are experiencing problems with hair damage or imbalance, this shampoo should be on your list of things to try.
