Shampoo & Conditioner

Shampoo is for the scalp and conditioner for the lengths. Most hair complaints — flaking, itch, limpness, even some shedding — start at the scalp.

What to know before you choose

Shampoo the scalp, condition the ends. Reversing this causes most flat, greasy-root complaints.
Medicated shampoos need three to five minutes of contact to work. Rinsing straight off wastes them.
Washing less often does not fix oiliness; it usually just delays it.
