Did One Treatment of Diode Laser, Got No Results — Why?

On arms/hands, only ~30% of hairs are in the growth stage (Anagen) during any single visit. The diode laser works on Anagen only — so consistent sessions catch follicles as they cycle, delivering long-term reduction.

PRINCIPLESEXPLAINED

How 808nm Diode Works (Simple Science)

808nm energy is absorbed by melanin in the hair shaft and follicle bulb. Heat disables the follicle’s growth structures (including stem cells) so it can’t regrow robust hair. Sapphire cooling protects the epidermis for comfort and safety.

808nm reaches the bulb efficiently while the sapphire tip keeps the surface cool.

Hair Cycles: Why One Session Isn’t Enough

  • Anagen (Growth): Hair attached to root — laser effective.
  • Catagen (Transition): Root shrinks/detaches — laser minimally effective.
  • Telogen (Resting): Follicle dormant — not targetable until it re-enters Anagen.
Key point: Only hairs in Anagen are disabled per visit. The others rotate into Anagen in the following weeks — hence the need for scheduled sessions.

Laser targets the Anagen connection at the bulb; transition/resting hairs aren’t responsive.

Arms/Hands: Exact Logic (~30% Treatable per Visit)

On arms/hands, roughly 30–40% of hairs are in Anagen in any given visit. The remaining 60–70% are in Catagen/Telogen and will be caught later as they rotate into Anagen. That’s why a single session cannot show full results.

Pie chart for arms/hands: 30% Anagen vs 70% Catagen+Telogen (replace)
Only ~30% of arms/hands hair is targetable per session — consistency = results.
Cross-sections: single session shows partial root damage; 6–8 sessions show shrunken/inactive follicles (replace)
Results come from progressive root inactivation, not just surface thinning.

What to Expect: Session Timeline

  • Session 1: Some shedding in 10–14 days; most follicles still active.
  • Sessions 3–4: Noticeable thinning; slower, finer regrowth.
  • Session 6: Significant visible reduction (~70–80%).
  • Session 8: Long-lasting reduction; smooth feel; occasional maintenance as needed.
Timeline: session 1 minimal change; 3–4 thinning; 6 major reduction; 8 smooth results (replace)
Each session eliminates the Anagen share present at that time.

FAQs

I did one session and saw no results — is it normal?

Yes. On arms/hands, only ~30–40% hairs are in Anagen per visit. Laser works only on Anagen hair, so results build across 6–8 sessions.

What gap between sessions?

Typically 4–6 weeks for arms/hands. Your clinician may adjust based on response and density.

Is 808nm safe for Indian skin?

With correct parameters and cooling, yes. Beautrix provides parameter guidance by Fitzpatrick type and body area.

Do I need maintenance?

Some clients benefit from 1–2 touch-ups annually due to hormones or lifestyle.
