What shampoo and conditioner has biotin in it?
Boost Biotin shampoo and conditioner has biotin in it. Biotin mainly helps to reinforce hair from the root to the tip making it an extremely wanted after ingredient in shampoos and conditioners.
None that I can think of. Take a biotin supplement if you are deficient. Or take a Multivitamin daily.
Biotin works best when ingested, not when applied topically. In fact your hair probably will not absorb much of the biotin in whatever shampoo you buy.
Pill is what works
