Hydrating serum
This is great, affordable, hydrating Sclap serum. I have dry Sclap a lot and this does feel good on the scalp when you apply it. It’s great if you’re starting to get into scalp serums.

Feels Amazing and Hydrating
I’ve only used this a few times but I LOVE the way it makes my scalp feel. It instantly makes my scalp feel more hydrated. I use it at night and it doesn’t make my hair greasy the next morning unless I use a lot.

Good for Dry Scalp, Just Don’t Use Too Much
I like this product and it has helped with my dry, flaky scalp. I have naturally blonde, medium-textured hair, and when I use a small amount it works well and feels soothing. However, if I apply too much, it can make my hair look greasy and feel weighed down. Overall, it’s a good scalp treatment as long as you’re careful with how much you use. A little definitely goes a long way.

Helps with itchy scalp, no buildup.
I'm really liking this stuff. I never had dandruff or redness or anything but I definitely got itchy scalp and a bit of sebum sometimes. The dry winter season is here and I recently shaved down to 2mm so my scalp is probably drying out faster than normal. I started using a few drops of this daily after my shower and it only took a couple of days to essentially eliminate any itching. I can't feel it on my scalp once I rub it in, and it doesn't seem to be causing any sebum buildup or anything. I highly recommend trying this if you just have an otherwise essentially normal, but itchy head.

Amazing for scalp shock
I have “scalp shock” after having a nanoplastia treatment done on my hair (never again 😩) my hair has been falling out in chunks for the past 9mos. This HA scalp serum has done wonders in repairing my scalp. It’s only been 1 week and I have had significantly less fall out.

Good product
It says to apply this everyday at night but I feel like it leaves my roots oily, overall I like the product I feel like it helped with my allergy

greasy
this product really does help your scalp, im significantly less itchy and flakey. the problem is fresh out the shower its extremely greasy. i have very thin hair and bangs that attract grease easily, so there is that. it may be better for thicker denser hair, but wouldnt recommend to anyone with bangs or thin hair

Awesome stuff
I'm a bald man. I have a very dry scalp to the point it's almost a medical condition. This serum made a drastic difference. It soaks right into my scalp. I have to use quite a bit to get my whole head. I massage it in and it disappears. My scalp looks and feels better. No more dandruff when I rub my head. In a sense, I'm lucky not to have hair to get in the way of applying the serum. I can't speak to what the experience of non-balds might be like. I have only been using this product a few days so I am applying it morning and night but I hope with regular use I will eventually only need it once a day. It has a slight scent out of the bottle, but it doesn't linger. The consistency is very watery and it does not leave a residue on skin.
