This is a nice product - it goes on well, dampens down any frizzy feel. It doesn't last that long though - the frizz feel does come back again. But it does make your hair feel a bit thicker. You feel like you're putting something nice on your hair though, as it's not oily or sticky and it gets absorbed quite quickly. I will probably buy it again as it's a handy size small bottle to carry in handbag for urgent frizz attacks when out and about.

Wonderful! It has stoped my hair shedding. However it would be great if I could purchase this at a higher volume per bottle as I get through it so quick

this is my first leave in serum ive tried for hair density and omg. ive only been using it for 3 weeks (i apply it every night) and im already getting baby hairs?! not only that- but it doesnt leave my hair looking or feeling greasy at all! the only downside would be the size of the pipette- its too small for the bottle so when you get towards the end of the bottle, the pipette cant reach the serum. i pour it onto my hands but obv that defeats the whole purpose of using a pipette in the first place. other than that though, i'd def recommend this to anyone with fine hair wanting to achieve that naturally voluminous, thicker-looking hair!

Great products with lovely scents. I especially like the hair thickening gel, which really works on my ageing thin hair. The lip balm too is very soothing. Minimal plastic, easy to order and lots of deals to keep you buying.

Hi June, Thank you for your feedback on our hårvekst Hair Density Serum. We really appreciate you sharing your experience. Afro-textured hair often requires more intensive moisture, and we understand that 30ml may not have been sufficient for your needs. Your input is valuable, and we’ll definitely take your suggestion for a larger, more hydrating formula into consideration as we work to improve our product offerings. Thank you again for helping us grow! 💚 Warm Regards, Andrea - team gruum

Bought this on sale as I'd unfortunately had some hair torn out around my hairline from some knotless braids. Used this almost everyday for about a month and I've seen a noticeable difference! The bald spot has really started filling out, it's hard to believe it was even there to begin with. I like the smell and how you can use it daily without it feeling greasy or like you've got lots of product just sitting on your scalp. Only downside is that with everyday use it does seem to run out fairly quickly, but I don't mind that much and have just purchased my second bottle.
