Biotin & Collagen Thickening Shampoo & Conditioner Set 300 Ml Each

I bought this to make my hair thicken. I still have some. I use it once a month.

Not impressed with this product, it left my hair feeling yucky, and found it difficult to comb my hair

Nice shampoo.

This is the best shampoo and conditioner I have ever used my hair is shiny and feels thicker.
