Great Addition if you're using an Irestore Helmet!

Wonderful serum for your scalp. I was diagnosed with a horrible hair/scalp disease - FFA....Before I could get my first treatment with my DermDoc, I purchased the Elite Helmet and starting using the serum and the hair supplement to help kick start thing. I was told I probably woun't regrown any hair in the scared areas...thankful that I caught this...read moreWonderful serum for your scalp. I was diagnosed with a horrible hair/scalp disease - FFA....Before I could get my first treatment with my DermDoc, I purchased the Elite Helmet and starting using the serum and the hair supplement to help kick start thing. I was told I probably woun't regrown any hair in the scared areas...thankful that I caught this before things got really bad - anyhow I started to have new hair growth in about a month...and this was happening before I had been on the meds for more than a couple of weeks. I wouldn't be using these products if I didn't feel they have helped. The serum also gives my hair a fuller look and body. I haven't missed a night with my helmet since I received it....Happy Customer....so far, it's all been worth the money and investment in the Elite Helmet!

Real results

Been using the serum for almost a year. My hair became thicker, longer, and shinier. Prior to use my hairbrush would 'fill up' in a matter of days and the natural part was getting wider. The serum works best, for me at least, when applied every 12 hours. It isn't sticky, has a light scent, and is easy to apply.

I gave this as a gift and I've been told is she feels that this is a tremendous self improvement step. Most things out there do not work ~ this does

Affordable hair serum

I really like the serum's viscous form, it's much easier to apply than liquid form. My hair loss state is at a late state evolution and not at young age. However, I noticed subjectively some baby hairs regrow at the temple. As conjunctive treatment, the helmet and serum stop hair loss and improve my hair in general.

Magic serum

This is the only hair serum that I saw results pretty quickly. I have a spot that started filling in after 2 months. I will continue to use and hopefully get my hair back to what it once was.
