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.

Wow — I’m seriously impressed! I’ve been using this for just under a week and I’m already seeing a huge difference. No more itching, no more flakes — my scalp feels calm, clean, and healthy again! I’ve struggled with dandruff and seborrheic dermatitis for ages, and this is the first product that’s actually worked this fast. Highly recommend!

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.

TLDR: works great but it loses a star because of how it makes my hair look dirty if i put too much/if it’s accidentally put on hair This has really helped my dry scalp a lot. I suffer with it along my hairline to where it’s visible on my forehead and under near the base of my head. But this does really make my hair look so much greasier even though it’s supposed to be a leave in serum and it makes look dirty right after I washed it. I have really thick hair so I do have to make sure i get it into all sections. i found it helps a little bit to not look as greasy is if you apply on your hand first, lightly rub it together, and then rub it directly on the scalp avoiding (like sectioning hair before hand) putting it directly on your hair.

If I could give this product 100/100, I absolutely would! This product saved my scalp. I struggle with psoriasis and have tried countless treatments, but nothing ever worked—until I found this gem. After just 2–3 uses post-wash, the redness and itching completely disappeared. I don’t usually write reviews, but this one deserved it. Truly a game-changer!

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

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

The ordinary products are anything but ordinary. They are exceptional. This moisturizing hair serum is 💯. I use it on day 2 and 3 hair when my scalp starts to get a little tight and itchy and it helps 100%
