actually works

Wish I would’ve taken a before photo. I was having thinning on my temples and decided to try this after looking at several different products. I’ve put it on my temples and throughout my hair just about every evening before bed for 2 1/2 months and the thin areas are pretty much filled in now with baby hairs. It doesn’t smell like anything or make my hair greasy. Just bought a second bottle.

Gave me dandruff!

I've never had dandruff before in my life but this serum gave me it BAD. It did the opposite of encouraging growth as I was pulling scabby bits out of my hairline which actually took hair with it.

confusing to apply

I’m not sure where or how to properly apply this serum. It’s more of a watery consistency than I expected. Directions say to massage a few drops into the scalp. When I use other hair products, I can cover a large area of my scalp with a few drops, bc the consistency is thicker. But not this product. A few drops of this covers a tiny fraction of my head. So should I use more than a few drops? I wish the directions were a little more specific as to where exactly to apply it.

It works so well, guys

I had 9 months (maybe a little longer) of telogen effluvium because of low ferritin. I almost lost half of my ponytail thickness. In addition, my hypothyroidism was poorly treated by my doctor (make them check your T3 levels!) and my estrogen and progesterone have been low since my last baby 9 years ago ( I'm essentially premenopausal). So my hair has been slowly getting thinner over the years benefits of those two issues. I started using this in August to help my hair grow back after I corrected my iron levels. My hair had stopped the telogen effluvium shedding-I don't think this would work if you haven't corrected an underlying problem. Within a month I think my normal hair fall decreased. Within 2 months I noticed short hairs sticking out where I parted my hair. Now at 5 months my hair feels thicker up top when I slide my fingers into it. I was only putting it on the crown of my head but I've started applying it on the sides and back to to help the hair grow back all over. Tbh I can't say if this will help specifically with menopausal hair loss/ decreasing shaft diameter, especially if you aren't on HRT. But I'm convinced it does increase overall thickness by decreasing hair fall and encouraging new growth.

Amazing Results in Just Two Days!

I bought this product last week for myself and my mum, and we are both so surprised and pleased with the results! After just two days, we noticed less hair falling out when brushing our hair and showering, which is amazing. I can also feel that my hair is getting stronger, and its texture feels healthier. We are both really happy with it!

It really works!

I bought this to add to my hair growth journey and use it on non hair was days and immediately started seeing results. I’ve always had thin hair but following a substantial weight loss suffered with my hair shedding more. I use it 4 times a week & it instantly feels thicker and can see lots of new growth
