- Asked by Survivor
- Official Answer By Nioxin - Brand EngageYou hair should start to look and feel thicker in about 60 washes with the System 4 kit. For breakage you will want to use Nioxin Anti-breakage Strengthening Mask. Anti-breakage Strengthening Mask promotes the thickness and strength of your hair by providing an effective defense against breakage. This nourishing hair mask delivers vital nutrients and hydration to your scalp, promoting healthier hair and protecting against breakage. To apply, simply dispense a small amount of Density Defend Anti-breakage Strengthening Mask onto towel-dried or dry hair. Gently massage it into the scalp and evenly distribute along the lengths of your hair, rinse and style as desired. For optimal results, combine it with your recommended Nioxin shampoo and conditioner.Was this answer helpful to you

Less hair fall
I'm very skeptical when it comes to products that claim to help with hair loss so I wasn't expecting this product to actually help, but it did within two weeks of usage. My hair was falling out in huge chunks due to high stress prior to switching to this system. Only problem is I don't see any baby ...

Good system but not seeing results
I have thick wavy/curly islander hair but I've noticed it thinning the past few years. I've used Nioxin for about 2 months now, the shampoo, conditioner, and the leave in treatment (System 4) and I honestly haven't seen any new growth... or thicker hair. It's made my hair appear healthier (shinier...

DO NOT BUY!! Caused me MAJOR HAIR LOSS
Hair Type Wavy Hair
I just wanted to write this review to help hopefully save anybody from any possible trauma from using this shampoo and conditioner system. I used the shampoo for a good six months just because I wanted to thicken up my hair. I actually didn't have any issues with hair loss? I just noticed that my hair was thinning. I consistently use this product and nothing else for that six months only to notice that my hair was coming out by the handfuls and not just small handfuls. It was literally just coming out By the bunches, even when I was trying to baby my hair and hold one end in a ponytail while I come through the ends with my fingers and it would just fall out. I have since used the Paul Mitchell tea tree, special shampoo, and conditioner, and now my hair barely is falling out at all. It's actually the least amount of hair I've ever lost in my life so I just want to warn anybody that wants to use this. That is a complete possibility that it will do the opposite of what you're trying to use it for. Before using the shampoo, my hair was on my butt and then afterwards it was to my shoulders and I just had to cut all my hair off because of it. It was so uneven and You could literally see through my hair when you were standing behind me I do not recommend.
