What it actually does.
Most scalp oils are too heavy or do nothing — Booster Oil is engineered to do something. It pairs the KIB peptide complex with rosemary CO₂ extract (which clinical research has compared favorably to minoxidil 2% on hair density at six months — without the topical irritation profile) and pumpkin seed oil, naturally rich in 5-alpha-reductase modulators.
The base — squalane and sunflower esters — absorbs in under two minutes, no pillow stains, no greasy roots in the morning.
Four steps,
once you've got the rhythm.
Part the hair
Take a small comb or your fingers and create three or four parts across the area you want to target — usually the crown and front hairline.
Apply 4-6 drops
Directly onto the scalp along the partings. Less is more — the oil spreads as you work it in.
Massage for 60 seconds
Use the pads of your fingers, not nails. Circular motions, gentle pressure. This is the most important step — circulation matters.
Sleep on it
Leave overnight. Wash out in the morning with your normal shampoo. Repeat 3 nights per week.
Five actives,
nothing extra.
Full INCI on the label, no hidden fragrance complex, no greenwashed marketing. Here's exactly what's in the bottle and why.
KIB Peptide™ complex
Signal molecule supporting follicle activity. Sustainably fermented.
Rosemary CO₂ extract
Clinical-grade rosmarinic acid. Comparable to minoxidil 2% in six-month density studies, without scalp irritation.
Pumpkin seed oil
5-alpha-reductase modulators. Traditional use, modern dosing.
Squalane
Lightweight base, absorbs in under 2 minutes. No greasy residue.
Sunflower & jojoba esters
Skin-identical lipids — repair scalp barrier between washes.
Real people, real timelines.
Less hair on my pillow
"I've been using it for 3 months. The first month felt like nothing. Month 2 I noticed I wasn't pulling clumps out of the brush anymore. Month 3 my husband mentioned the part looked thicker — and he doesn't say things to make me feel good."
Doesn't make hair greasy
"I have fine, oil-prone hair and was nervous about an oil. It really does absorb fast. I do it Sunday/Tuesday/Thursday nights and Friday hair is still clean enough to skip a wash."
Smells nice, gentle
"Light rosemary scent, nothing perfume-y. My scalp is sensitive and this didn't trigger anything. 4 stars not 5 because I'm still in month one — I'll come back in two."
