CURLVEXA™ DoseLine
Precision Scalp Serum Applicator
Part. Press. Apply. The precision scalp applicator designed to put your serum where it actually belongs. Not all over your hair, not running down your forehead, and not pooled in one spot.
YOUR SCALP SERUM SHOULDN'T END UP MOSTLY ON YOUR HAIR.
You bought the serum for your scalp. But the usual routine involves opening the bottle, tilting your head, dropping too much in one place, missing the scalp, coating the hair, and wiping runoff off your forehead. The formula may be premium—the application method usually isn't. DoseLine was designed to fix that.
3 TOOLS BECOME 1
Traditional routines require a tail comb, serum bottle, dropper, fingers, mirror, and towel. DoseLine merges them into one seamless mechanical device: Part. Press. Glide.
Why DoseLine Feels Different
01 — Precision Parting Tip
Features a slim tapered tip designed to help separate hair cleanly and create a visible application path. The same tool creates the line and follows it.
02 — Controlled Dose Release
Droppers are easy to overuse and spill. DoseLine is engineered for controlled dispensing: press once, release a small amount, and build gradually.
The 6-Step Application Routine
- STEP 1 — FILL: Open the refillable reservoir and add a compatible lightweight, low-viscosity scalp serum. Close securely.
- STEP 2 — LOCK & PRIME: Unlock the dispensing system and prime gently if needed until a consistent amount reaches the tip.
- STEP 3 — PART: Use the tapered tip to create a clean section until the scalp line is visible.
- STEP 4 — PRESS: Press the dose control once to release a small, measured amount.
- STEP 5 — GLIDE: Place the application tip against the exposed scalp and glide gently along the part line.
- STEP 6 — MOVE: Create your next section and repeat for a structured routine.
More Precision. Less Waste.
Stop flooding your hair strands. Target your scalp directly where transformation begins.
