I love that this made

[This review was collected as part of a promotion.] I love that this made my hair feel more manageable. It feels like silk and before I used the conditioner, hair serum, and the shampoo, my hair used to be really frizzy so full of static that I saw light when I used a wooden comb on my hair at night. Now I don't have that problem anymore and it's easier to comb.

I have noticed far less

[This review was collected as part of a promotion.] I have noticed far less breakage in my hair after a few weeks of using this. My only complaint is that the bottle is smaller and I have a lot of hair (below mid-back), so even just using it on my ends requires a bit of product.

COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Treatment

[This review was collected as part of a promotion.] I really like this hair bonding treatment. I purchased the jumbo size this time because it is so good. Very nourishing for your hair without weighing it down. It feels really good and does not irritate my sensitive scalp. I would definitely recommend this.
