“I’m halfway through a bottle of this serum and so far I haven’t noticed any improvement in hair strength or growth - I’ll keep going and see what happens at the end of the bottle.”

“Very nice texture not sticky at all, has a pleasant citrus scent. I have just started to use it so it’s a bit early to see any results.”

“haven't noticed any particular benefit as yet, would have liked instructions on how much to use and how often as this would have helped significantly. Love your other products; candle, room freshener and diffuser.”

Hi there, Thank you for sharing your thoughts on our hårvekst Hair Density Serum. We’re so glad to hear you’re enjoying our candle, room freshener, and diffuser! For the serum, a few drops can be added to either damp or dry hair along the scalp and hairline, and gently massaged in with your fingertips. It’s best to leave it on for at least six hours, and a tingling sensation may gradually develop where applied. Daily use can give the best results. Everyone’s hair journey is unique, so changes may appear gradually over time. Warm Regards, Andrea – team grüum

“Hair Density Serum....I thought I would give this serum a go as I've tried lots of other products claiming to thicken/help hair grow...very easy to use, it has a pipette you fill up and use where needed and gentely massage in...unfortunately it hasn't helped my hair at all.... :-( Maybe like others they are for ''younger'' hair and not people in the their 70's”

“I was worried it might sting, smell bad, or drip down my scalp, but it doesn’t do any of that. No stinging at all, and it stays put. The smell is quite strong at first, but it’s not chemical in the slightest—more like a peppermint/herbal scent. I’ve got ASD and I’m sensitive to smells, and this has been absolutely fine for me. Really easy to use, and no side effects (which I’ve had with other treatments). I haven’t been super consistent yet, so can’t really comment on final results just yet.”

“My first experience of Gruum, and I got to try this product for just £1. Lovely service and fast delivery. The serum itself smells great and is easy enough to use, but I can't say I've seen any difference in hair density yet. I would probably need to continue to use it a while longer and see how it goes longer-term before I could give it an honest 5-star review! But thank you Gruum for giving me this opportunity to try your products.”
