- Q
I'm new with this line and trying to figure out what works best and what are the stages of application. I'm using System 2 and wanted to ask if I need both the Hair Booster and Diamax, (for my thinning hair due to thyroid, menopause and chronic illnesses), and if so in what stages should each be applied?
- Asked by Tammy
- Official Answer By Nioxin - Brand EngageOn days that you shampoo: Apply in the following order 1. Shampoo 2. Conditioner 3. Hair Booster 4. Scalp & Hair Treatment 5 Diamax. On days you do not shampoo apply in the following order: 1. Hair Booster 2. Diamax. It is not recommended to start too many products at once. You may not need them all and if you do not like one it is harder to determine which product you dislike. Diamax: Diameter-Boosting treatment with HTX technology scientifically designed and tested to increase the thickness of each of your existing hair strands for fuller looking hair. HTX technology includes ingredients which provide notable benefits for skin care such as caffeine, panthenol and niacinamide that deliver visibly thicker-looking hair.

- Q
I am 70 years old and have always had fine hair. Just within the last year I tried a product called Got Grit in the crown of my hair where I have an unwanted part in my hair. Since using this product my hair has started thinning. Will this hair booster help my hair grow out again. I have stopped using the Got Grit.
- Asked by Peggy
- Official Answer By Nioxin - Brand EngageThe Hair Booster could be beneficial in thickening and lessening breakage of the hair. however if the Got grit clogged the hair follicles, causing them to suffocate and dye, you may actually need one of the the system shampoo to clean them out and let the hairs below breathe and grow. It would not hurt to have the conditioner from that same system to stimulate the blood flow which feeds the hair follicles. For more questions please call Nioxin at 800.935.5273.Was this answer helpful to you

Hello I just bought the whole system and can't wait to try it. My question is, I have been doing a rice water rinse for about a month now. Would it still be ok to do the rinse or should I discontinue and only use the hair booster and the scalp treatment. Thank you.
- Asked by Dj
- Official Answer By Nioxin - Brand EngageIt would be recommended to stop the rinses until you know how the Nioxin products work on your scalp and hair alone before adding a service that may or may not interfere, as our products are not tested in conjunction with the use of rice water rinses.Was this answer helpful to you

I recently lost all my hair from chemotherapy. is this good to help my hair grow back?
- Asked by leash
- Official Answer By Nioxin - Brand EngageNioxin System Kits are always the best place to start. The idea is to create the optimal growing environment for your hair. This is done by cleaning out hair follicles, stimulation of the scalp and adding antioxidants and botanicals to keep the hair and scalp healthy. Nioxin system kits are formulated for certain hair types. Please use the following information to figure out which system is right for you. Most likely you would start with system 2. Normal to thin looking hair. System 1- Formulated for fine hair that is not color treated, bleached or permed System 3- Formulated for fine hair that has is being colored, permed or bleached System 5- Formulated for medium to coarse hair- Great for both natural and chemically treated hair Noticeably thinning hair- has UV protection as an added benefit System 2- Formulated for fine hair that is not color treated, bleached or permed System 4- Formulated for fine hair that has is being colored, permed or bleached System 6- Formulated for medium to coarse hair- Great for both natural and chemically treated hair Please call Nioxin Technical support at 800-935-5273 for additional information and product recommendations.

- Q
What is the order of using a full kit (shampoo, conditioner, treatment) and then also Diamax advanced. How long do you wait between applying each? The other of ALL Nioxin products and which go together is confusing.
- Asked by JT
- Official Answer By Nioxin - Brand EngageManufacturer’s directions are to use these three products daily for the fastest results. Being not everyone shampoos daily, please note you will still see the results, just not as quickly. In the first few weeks of use, the product is cleaning out clogged hair follicles. During this process, you may notice extra shedding. This is the hair that was unable to shed due to being stuck in the follicle being released. A new hair will be allowed to grow in its place. The conditioner should remain on for 3-minutes if time allows. Next, shake the Scalp and Hair Treatment and apply to towel dried hair at the scalp, followed by gently combing through hair. You do not wash this product out. Please note that the conditioner along with the scalp and hair treatment stimulate the scalp, often causing a tingling sensation. A slight red flush to the skin may be noticed due to the blood flow being raised to the surface. Redness should not last more than half an hour. After the use of the scalp and hair treatment, you may style your hair as usual. Do not use the scalp and hair treatment on days you do not shampoo. You may add the Diamax to your hair after applying the scalp and hair treatment whithout waiting. On days you do not shampoo feel free to use the diamax at any time prior to styling.

Hello, I will be starting the system 4 kit and wanted to add this to the regimen, can you do that? The kit comes with a foam leave in. When do you use that and when would I use this serum booster? And can they all be used daily? Thank you!!
- Asked by Reeshy
- Official Answer By Nioxin - Brand EngageYes, you sure can use them together. On days that you shampoo and condition you will use the scalp treatment. On those days apply the hair booster first and then follow with the scalp and hair treatment. These products are meant for daily use, and the booster can be used twice daily.Was this answer helpful to you

- Q
I use Nioxin shampoo, conditioner and the scalp therapy. Would I use the hair booster in place of scalp therapy? Or do I use after applying the scalp therapy? I wash hair in the morning so this is mainly for that time. I understand that I would apply this product again at night which can go on dry hair.
- Asked by Maria
- Official Answer By Nioxin - Brand EngageThank you for reaching out. This is a great question. apply the hair booster first followed by the scalp and hair treatment.Was this answer helpful to you
- Q
Hi! How does Nioxin Intensive Therapy Hair Booster compare to Nioxin Scalp Renew. Which one works better for thinning scalp? I am not able to get the Scalp Renew treatment at my salon right now. So at the moment, I am interested in an at home product that will help with thinning scalp hair. Or do you have a different recommendation? Thank you!
- Asked by Ric
- Official Answer By Nioxin - Brand EngageThe hair Booster is for specific areas of concern, such as low density areas. It is a leave-in treatment that creates a barrier to protect the cuticle against breakage. Scalp Renew is for dry scalp, itching, flaking and exfoliates the scalp. It helps remove debris so the hair may grow without getting clogged. I would say the Hair Booster or even Diamax Advanced may be the best choice.Was this answer helpful to you

Waste of money!!!
You get ONE ounce of this in a bottle that could probably hold 6 oz. Says to use 2x a day. One oz. does not go far AND I saw no results whatsoever. Should be packaged with more product to be able to tell if it works--you run out before you've had time to tell. DON'T WASTE YOUR MONEY! I regret buyi...

The product is comfortable and easy to use, it also didn't weigh down my fine hair. However, I have not seen a big impact on the thickness of my hair from using the product.

I was excited to try this booster serum, to help my hair where it was thinning. Unfortunately, even though it is expected to have a little redness and irritation, it was too much for me. Not sure if that is the normal expectant, or if I was having an allergic reaction.
