I've been using Nioxin System 4 Shampoo for about a month, and the results have been remarkable.

It contains ingredients like peppermint oil and salicylic acid, which invigorate the scalp and promote a healthier environment for hair growth. nioxin.com +1 InStyle +1 I appreciate that it's safe for color-treated hair, and I've noticed no fading or dryness since incorporating it into my routine.

Stopped My Hair Loss!
My hair was coming out in clumps every washing. I wash every other day. It was begining to feel panicked. Thankfully a friend suggested I try Nioxin. In less than 2 weeks, it went from a handful, to almost nothing. I'm so grateful for this amazing solution. The picture shows the before and after hair loss from each washing.

Use with Nioxin 4 shampoo for best hair loss reduction
When used along with Nioxin 4 shampoo, this product does indeed slow hair loss. It also greatly reduces the horrible tangles I used to have after washing my hair. The scent is lovely. Due to its high cost, it's a luxury item for me but I have yet to find a cheaper product that works as well.

Funciona
Funciona con el shampoo , me ayuda a que mi cabello no quede tieso después del shampoo. Recomiendo los dos productos juntos el shampoo y condition. Me lavo el pelo dos o tres veces la semana. Los demás días recomiendo que uses gorro para bañarte. Mi pelo es largo y tarda mucho tiempo en secar por si solo , no recomiendo usar el secador en lo personal debilita mi cabello y se quiebra.
