Biotin thickening treatment

This is an amazing product that gives my hair volume and softness. My hair is no longer frizzy and flat. I will continue to use this product and am glad I tried it.

Scent isn't quite right

I like this product just fine but I'm always reluctant to use it because the scent is off to me. I have many other products in the Dark Waves scent and I love it in everything else I have, but in this product it vaguely reminds me of black licorice.

Excellent help for fine hair

DALLAS Biotin Thickening Treatment has been a great addition to my hair care routine. I use it about once a week and it leaves my hair with more fullness and body. It also smells so good which is a bonus!
