I have healthy, loosely curled hair that is fine textured and it's thinning terribly. I've been on a high dose of medication for hypothyroidism for 20+ years. I've used Nioxin before years ago before I was diagnosed. Only one type of product was available here... Which formula should I start using?

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...

Made my hair feel like straw
Hair Type Wavy Hair
It did make my hair fuller but really dried it out.
Great product!
Hair Type Straight Hair
Bought this kit and starting using as a result of increasing hair loss and breakage. Not sure? Old age? Menopause? All of the above. Have been happy with the results in seeing decreased breakage and new growth. Enjoying the shampoo and conditioner more than the added foam. The foam makes kind of a sticky, crunchy mess of the hair and was told by my hairdresser never to use prior to going for highlights as it can interfere and cause some unexpected color change (i.e., green). Will also say the peppermint scent is an eyeopener in the morning!
Yes buy again
Hair Type Wavy Hair
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
