Styling load
Tension, not just genetics
Tight braids, cornrows, weaves and edge-laying put sustained pull on the follicle. Dr. Reju-All targets the scalp environment those styles stress — the hairline, the parts, the nape.

Built for the hair you actually have
Most scalp serums
were never tested
on your hair.
Type 4 hair carries a different load: tension from braids and weaves, weeks between wash days, product sitting at the root, heat and chemical processing. Dr. Reju-All was formulated around that reality — not adapted to it afterwards.
Wash-day gaps
Long stretches between washes
Protective styles mean two to eight weeks of build-up, sweat and dryness at the root. A water-light serum layers in between wash days without residue or flaking.
Chemical & heat
Processing & heat
Relaxers, colour and regular heat leave the scalp barrier compromised long before the strand shows it. Ceramide and panthenol support recovery at skin level.
Let's talk about it
CCCA is common.
Talking about it
still isn't.
Central Centrifugal Cicatricial Alopecia is one of the most common forms of scarring hair loss in women of African descent — and it rarely announces itself. It starts quietly, at the crown.
- It usually begins at the crown and moves outward, often long before anyone else notices.
- The early signs are easy to explain away: tenderness, itching, burning, or a part that keeps widening.
- Because it is a scarring form of hair loss, time matters more than any product. Early diagnosis is what protects the follicle.
- A calm, cared-for scalp is the foundation everything else is built on. That is the part Dr. Reju-All is for.
Dr. Reju-All is a cosmetic scalp-care product. It is not a treatment, cure or preventative for CCCA or any other medical condition and does not replace medical care. If you notice tenderness, persistent itching, a widening part, or hair that isn't growing back — please see a dermatologist, ideally one experienced with textured hair.

The difference is in the details
Grounded in Korean formulation standards. We don't skip the parts that decide whether a formula actually works.
Industry standard
- High-ppm claims with nothing shown on absorption
- Plant-derived "PDRN" substitutes at low purity
- Spec-sheet marketing, weak real-world delivery
Dr. Reju-All
- 1,200 ppm salmon-derived PDRN at 99% purity
- Low-molecular-weight fractions sized for the scalp
- Concentration chosen for absorption, not for the label
Industry standard
- Single-active formulas chasing one mechanism
- Actives that destabilise weeks after opening
- Alcohol-heavy carriers that dry an already-stressed scalp
Dr. Reju-All
- PDO paired with copper tripeptide-1
- Stability-tested through the full open-jar period
- Alcohol-free water base with panthenol and ceramide
Industry standard
- Oils and butters that sit on the strand and build up
- Droppers that soak the hair before they reach skin
- Fragranced formulas on a scalp that's already irritated
Dr. Reju-All
- Water-gel that absorbs in under 30 seconds
- A slim ball that rides inside the parting
- Fragrance-free and dye-free — safe between wash days
Inside the formula
Light enough for every
night. Serious enough
to feel it.
Clear, weightless, unscented. It disappears into the scalp in seconds and leaves nothing behind — no slip on your edges, no film under a wig cap, no residue on week three of a protective style.
Shop the serumThe ritual
Thirty seconds.
Every night.
Consistency beats intensity. This is designed to slot into the routine you already have — including the weeks you're not washing.
01
Part
On a dry or towel-dried scalp, part your hair into four to six sections — crown first, then the hairline and nape.
02
Apply
Press the ball to the scalp and run it down each parting, twice. You should feel it land on skin, not soak into hair.
03
Massage
Thirty seconds with fingertips, never nails. Nightly on loose hair, every other night on braids, locs or a sew-in.
Give it one full cycle — around twelve weeks — before you decide. Take a crown photo on day one so you're comparing to something real.

★★★★★
"My crown has been my sore spot for years — literally. This is the first thing that doesn't sting when I put it on a tender part. Ten weeks in and the section behind my part finally looks less see-through."
Amara O.Verified · 10 weeks in
★★★★★
"I keep knotless braids in for six weeks at a time and every other serum turned into gunk by week two. This one genuinely disappears. No smell, no slip, no flakes when I take them down."
Nia B.Verified · Protective styles
★★★★★
"The ball is the whole thing for me. It sits right inside my braid parts, so I actually get down to my scalp instead of wasting half the tube on my hair. Small detail, completely changes whether I use it every night."
Zainab K.Verified · 4C, fine density
★★★★★
"Post-relaxer my scalp was permanently angry. Two months of this and the itching has calmed right down. I'm still seeing my derm — but this is the part I can actually control at home."
