Biotin Boost Thickening Shampoo

Intially, I was satisfied. Left my hair clean and with volume. I developed an allergy quickly so I had to throw out my second bottle. But for anyone who wants biotin, it’s a good choice.

Has an overpowering scent. This shampoo claims to be a thickening shampoo. I found it to be a harsh cleanser that left my hair feeling dry. Added no volume or thickening to my hair.
