After a week trying a new red light therapy cap, hair on the back of my head drastically shedded. I stopped the cap, then along with supplements I looked at serums. Nutrafol is pricey, so I got The Ordinary's Multi-Peptide. While I wait for my hair to grow back (fingers crossed), The Ordinary's serum is gentle. I use it generously at night & a little in the morning. I'm not sure yet re: hair regrowth, but it does create an illusion of increased thickness, so the hair loss doesn't look as prominent. My hair also feels stronger when I run my hand thru my hair, despite the ongoing shedding.

I love this, I’m on my sixth bottle, each lasts me about two months, I use almost daily and have to force myself to skip days, one of the only products I’ve noticed significant regrowth and reduced shedding, it’s light and non greasy, I do mix in my own Ahk-cu, but feel like this is the perfect serum to do that, all others I’ve tried leave my hair crunchy or oily.

I’m a woman in my sixties with heavily thinning hair. I thought i could just start using Rogaine and everything would be fine. Sadly, once a woman goes through menopause, she is missing an enzyme on the scalp that activates the Rogaine or any topical minoxidil product (and oral use of minoxidil after age 65 is not recommended due to heart issues). So I am trying this product, and a prescription retinol cream along with the Rogaine to try and jumpstart my scalp. I do believe this product has helped fill-in baby hairs at the temples and around the hairline of my face (but not down my part or top of head yet). This product has virtually no scent and is not oily unless you really overuse it. I use only drops of this around my hairline and down my part-line. I do not place it on my hair, but directly onto my scalp, a drop at a time and kind of press it into my scalp. I do this at bedtime and leave it in all night. It actually adds a little texture at the scalp when I wake up in the morning, and my thin hair doesn’t look so flat. I don’t need to wash it out as long as I haven’t applied too much. I also use this after a fresh blowout and just barely dotted it on the thinning areas of my scalp, and somehow, it gives a thicker look to the root area. It dries fairly quickly.

I have been using this ever since I got it at the end of September and have almost finished the entire bottle, I really want to give this a higher rating. I don't know if I just need to give this a longer time for me to see any results, I will say when I do put it on at night in the morning my hair is left feeling refreshed and more volumized. I really can't say that I have new hair growing in after I have been shedding a lot ever since May. I can't really tell if its cause of my diet or cause I am a little less stressed or due to health that my shedding decreased. I will continue to use it but again Im not sure if I see my hair thickening, I do feel like my hair is definitely volumized in the morning when I wake up.

My favorite hair serum, and this is my third bottle! My hair sheds less every time I start use this product, and it doesn’t make my scalp feel irritated.

Did nothing for me... Used it 3x a week for 2 months. Applied topically at night on a dry scalp. I would only use this at night, so it has time to dry. Otherwise expect oil slick hair! I used half a dropper on each side of my scalp. It really did nothing. A lot of these before and after photos just look like greasy hair vs freshly washed and dried hair; of course it looks fuller. Greasy hair clumps together. Enough of these magic potion solutions... I'd say the only reliable solution is to figure out what is causing the balding to begin with. Start with your doctor before turning to these hyped up miracle products.
