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.

greasy residue
If you want to walk around with oily hair then use this. LOL.
Used it after the shower and had already done my make up, started drying my hair and was annoyed I had to get back into the shower to wash it out. There was no way to walk around looking like that. Hair was very oily looking.

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.

gifted by theordinary. I’m still not totally sure how I feel about this yet. I like the idea of it and I’m curious to see how the growth looks over time, but I haven’t used it long enough to really tell. I do have super thin hair though, and I’ve noticed it can make my roots look a little greasy. Not giving up on it yet, just still deciding if it’s for me.

pretty good
The lightweight serum absorbs quickly without leaving any greasy residue, and it feels comfortable on the scalp. Over consistent use, I’ve noticed my hair looks a bit fuller and seems healthier overall — not a dramatic transformation, but definitely an improvement in density and strength.gifted by The Ordinary

softer
I’ve been using this serum for a few weeks now, and I’ve started to notice that my hair feels a bit fuller, softer, and overall healthier. It has a very lightweight texture, doesn’t leave any greasy residue, and is really easy to apply, especially at night. I like that it doesn’t weigh my hair down or make my scalp feel oily the next day. That said, the results are gradual and definitely require consistency and patience. It’s not a miracle product, but I do think it makes a difference over time. Overall, I’m happy with it and would recommend it if you’re looking to improve hair density slowly.gifted by The Ordinary
