    "No smell, no weird texture, clearly largely water based, perfect. After years of using Minoxidil, i kept losing my hair, and had those well known bad side effects on my skin. No side effects at all with the this."

Reviews Summary
Customers say this scalp treatment shows promising results for many users. Many reviews mention seeing baby hairs and reduced shedding within a few weeks to months of consistent use. The lightweight formula absorbs quickly, though some note it can leave residue that requires morning washing. Reviews are mixed on texture - while some find it non-greasy, others mention flaking or buildup. Most users emphasize patience is key, with noticeable changes typically appearing after 2-3 months of regular application. A few report scalp sensitivity or irritation.

    IT WORKS!

    It works, it really does! I’ve been using it for 2 months and I’m definitely seeing improvements all around. Mind you, I use it about 4 times a week so waaay less than what INKEY suggests so it took more time for me to notice changes. About two weeks after I started to use it, I could already see that I was losing almost NO hair when I washed them (this was a huge concern of mine, cause I was starting to notice big patch of hair in my shower and ALSO in my brush after every time I washed them before starting to use this treatment).

    Around the same time, I could clearly see that my hair were stronger and definitely not as thin as they used to be. My ponytail was fuller and my waves more defined, I could really FEEL the change when I brushed my fingers through my hair!

    After about a month and half, I could notice the baby hair along my hairline and in the place of my scalp where I was balding! It took some time but as a pharmacist I know that it’s completely normal, I even expected to see baby hair growing in 3/4 months so you can understand my excitement when I saw them after 1.5 months!

    As a pharmacist, I’m also using supplements pills cause I know how important that is but I can 100% affirm that the INKEY treatment did its part in preventing balding and improving my hair thickness and growth.

    Did the job great.

    One thing I love about this product is that it dries down pretty quickly. I was afraid of gling to bed with a wet head but it was dry within minutes and wasn't uncomfortable to sleep. My scalp felt great the next morning after washing.
