HYDRO BALANCE SCALP SERUM
-
I use this right after the Density Boost Shampoo and follow with the Density Boost Conditioner. The three together have completely eliminated my dry flaky scalp and my hair feels thicker at the roots.
-
Pairing this with the Density Boost Conditioner has been a game changer for my protective styles. My scalp stays hydrated and itch-free for days between washes.
-
I was spending a fortune on medicated shampoos. This serum did more for my dry scalp than any of them. Simple to use and actually works.
-
I paired this with the Density Boost Shampoo and my hair stylist was shocked at my scalp improvement. No more redness or dryness.
-
Really effective for my dry winter scalp. I apply a few drops after washing with the Density Boost Shampoo and the hydration lasts until my next wash day. Only wish the bottle lasted longer.
-
Eight weeks of nightly application and my scalp is a completely different environment. No more tightness, no more flaking, and my hair stylist says she can see new growth coming in.
-
Made my hair look greasy near the roots if I used too much. Had to figure out the right amount which was frustrating.
-
My thinning crown area has shown real improvement after three months. The rice water and niacinamide combo in this formula is brilliant. My dermatologist is impressed with the results.
-
My scalp was constantly flaky and itchy. This calmed everything down within a week. I use it after every wash and the difference is night and day.
-
Finally something that treats the scalp, not just the hair. My itchy winter scalp is a thing of the past.
-
I didn't realize how much my dry scalp was affecting my hair quality. Since using this, my hair looks shinier and healthier from the root.
-
I have psoriasis patches on my scalp and this has reduced the flaking significantly. Gentle enough to use alongside my prescription.
-
Perfect for winter when my scalp gets so dry it hurts. This hydrates without making my hair greasy. I apply it at night and wake up with zero flakes.
-
Helps with scalp dryness but I wish the applicator tip were narrower for better precision. Product itself is great, just a packaging note.
-
My dermatologist recommended a scalp serum and I found this one. My scalp feels balanced, not oily, not dry. Hair shedding has decreased too.
-
The dropper makes it easy to target my problem areas. My dry, tight scalp feels nourished and comfortable now.
-
Color-treated hair and a sensitive scalp is a tough combo. This is gentle enough for both and keeps my scalp comfortable between washes.
-
Six months in and my scalp health is completely different. Less itching, less flaking, and my hair stylist noticed my hair growing in thicker.
-
Three bottles in. My scalp health completely transformed and my hair is growing in thicker and stronger.
-
Lightweight, non-greasy, and actually works. My scalp feels balanced for the first time in years. Niacinamide in a scalp product is genius.
-
Rice water for hair is the real deal. My thinning edges are filling in and my scalp doesn't itch anymore. Using it daily after washing.
-
My scalp was so itchy and flaky from hard water. After three weeks of this serum, the irritation is completely gone. Hair feels healthier from the root.
-
Using this after every wash and my scalp feels so much healthier. Less shedding in the shower drain too. The rice water really works.
-
Average scalp serum. Works okay for mild dryness but my severe dandruff needs something stronger.
-
My postpartum hair loss was devastating. This serum calmed my inflamed scalp and I'm seeing new growth at three months in.
-
Solid product for scalp health. The applicator could be more precise but the formula itself works well on my dry patches.
-
Good scalp treatment. Takes a few weeks to see results but my flaking has definitely decreased. Wish the bottle were bigger.
-
My color-treated hair was causing major scalp sensitivity. This calmed everything down without affecting my color.
