- Q
My hair is getting very thin and keeps breaking when i brush it. How fadt will I notice my hair getting thicker fuller a d not breaking off? This product will help with thst correct?
- 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...

This makes my hair very soft. I can't say it has helped with hair growth and I have been using the conditioner and shampoo for years. I wish it would. On the upside; I recently saw my dermatologist for my yearly skin cancer check, and she thoroughly searches you from head to toe. She said my hair was extremely healthy.
My hair is THICC but SO DRY!
Hair Type Wavy Hair
I absolutely love this product for the intended purpose of thickening my hair, but holy cow, my hair is now like HAY. It is so incredibly dry, and I struggle to untangle it and had to order an Unbrush to even work through it all. The product really works for what people want to buy it for, but wow, my hair is truly the driest it has ever been. But if you want your hair THICK? This may work. Just be wary about overwashing and be sure to treat your hair, especially if you have long, color-treated hair like I do.
Great conditioner

Good conditioner - makes your scalp tingle
Reformulated—thinner product
Ive been using Nioxin shampoo and conditioner for advanced thinning/chemically treated hair for years. The new system's condition is such a disappointment. The consistentency is significantly thinner—like a watered-down version of the old formula. It used to be moisturizing enough for my color-treated & permed hair. This one leaves my hair feeling drier overall and my ends rough. Now, I have to follow up with a hair mask from mid shaft to ends. I will continue using the shampoo, but this conditioner is just such a let down.
