Best product that I found so far!!!
Size: 16 Fl Oz (Pack of 2)
I purchased this shampoo and conditioner and honestly, it has pleasantly surprised me. After the first few weeks, I noticed my hair felt softer, looked shinier, and was much easier to manage. My hair tends to be a bit dry and prone to shedding, and I feel like this product has been helping to strengthen it over time.

Smells good.
Size: 16 Fl Oz (Pack of 2)
I used this ser along with a biotin hot oil treatment to try and repair my hair. Im 10 months postpartum and breastfeeding so my hair is not super healthy, but this has helped a little. The smell is nice. I bought it on sale, I don't think I'd pay the whole 35$ for it, but I also just started a week ago. The shampoo is extremely lathering, and thicker than the conditioner. Im impressed more with the shampoo, as I feel the conditioner lacks in body and softening.
