What did Elon Musk use to regrow hair?

This question lands on nearly every laser-therapy search, so it is worth answering directly even though the honest answer is not LLLT. Public reporting and his own past comments attribute the regrowth to a hair transplant dating to the late 1990s or early 2000s, not to laser caps. For readers actually weighing laser therapy, the published evidence points to a modest, real density benefit in pattern hair loss, not a transplant-level transformation.

Are laser hair growth caps safe?

Laser hair growth caps are generally safe, with documented side effects that are mild, transient, and in the low single-digit percentages, mainly dryness, itching, and brief scalp tenderness.[1:7] The bigger safety question is screening rather than the light itself. Skin cancer on the scalp, photosensitizing medications, pregnancy, and photodermatoses are genuine contraindications a careful provider checks before recommending a cap.

What hair cannot be lasered?

Laser therapy cannot regrow follicles that are no longer viable. Areas of complete baldness with no dormant follicles, scarring (cicatricial) alopecia, and zones of active scalp inflammation will not respond, and the contraindications above apply. A hair and scalp analysis confirms whether living, dormant follicles are present before any program begins.

How long does it take for a laser cap to work?

A laser hair growth program typically shows reduced shedding from around month one and visible regrowth from around month three, with a standard course running over roughly six months.[4:2] In-clinic protocols can compress the cadence under supervision, while consumer caps used inconsistently often extend it.

Are the side effects different for women?

The documented side-effect profile is the same, but the screening is what changes. Postpartum hormonal shedding and underlying causes like thyroid or iron issues should be ruled out first, since a cap will not address them, and supervised dosing handles the cycle-related scalp sensitivity a fixed-output device cannot.
