Review: For all the Menopause Mamas - I was so impressed with Nioxon. I preferred just using the spray because I felt like that made the most difference, but the shampoo and conditioner are great also. Between being on a GLP-1 and menopause, my hair was going through it! I was losing a lot quickly and was devastated. I started using this set and saw a difference within the first month, and month 2 was awesome! It won’t happen all at once so you have to be patient but it was definitely worth the wait!
Review: Definitely helps hair growth - Great product

## Questions & Answers

**Q: Is this a cream or spray liquid?**
A: Its a liquid you spray onto your scalp.  Its been a while since I've used it,  but I believe you spray on and kind of rub it into your scalp and leave it in your hair.

**Q: can you use nioxin scalp repair on dry hair?**
A: I would be happy to answer this question for you. Our Nioxin Scalp and Hair Treatment is to be used on damp towel dried hair after the shampoo and conditioner application and rinses. You would want to use 2-3 pumps on your finger tips and massage into your scalp. Wait one minute then style and use any products or tools you normally do. 
I hope this answered your Nioxin question today. Have a great day!

**Q: Does the scalp & hair treatment gets put in wet or dry hair?**
A: This is a really great question I am happy to answer for you. You will apply our Nioxin Scalp and Hair Treatment after Shampoo and Conditioning on towel dried hair so it will be damp. I recommend you use 2-3 pumps on your finger tips and massage into your scalp. Allow 1 minute and the apply any styling products or heat elements as you normally would.

I hope this answered your question today.
Have a Wonderful Nioxin Day!
