Results come in three phases. Within 2–4 weeks you'll notice less shedding as the channels stabilize the hair bulb. Between 3–6 months, dormant follicles enter the growth phase for visible density. Hair is slow-growing tissue — any product promising overnight results is ignoring physiology.

No. The stamp creates a clean vertical entry and exit at just 0.5mm. Older rollers can cause track-mark tearing; our micro-channels trigger a healing response (increased blood flow) that typically fades within 2 hours.

Yes. Every needle head is surgical-grade stainless steel. At 0.5mm the needles don't enter the bloodstream. Soak the head in 70% isopropyl alcohol for 5–10 minutes before and after each session.

0.5mm is the "goldilocks" depth — 0.25mm is too shallow to reach the follicle bulb, while 1.5mm is intended for clinical scarring and causes unnecessary bleeding. 0.5mm is the maximum depth for safe, painless home use that still triggers the dormant-growth response.

DearRoot strengthens the root environment rather than masking symptoms. Hair always needs ongoing nutrients, so we recommend a once-weekly maintenance phase after month six to keep follicles in their growth stage.

Yes. The Root Activator Serum is gentle and works at the scalp, not on the strand, so it won't strip or fade color. We recommend waiting 48 hours after coloring before your next session to let the scalp settle.
