What occurs to hair follicles with regular laser treatment?

With regular laser treatment, hair follicles become damaged and may not regrow. The mechanism behind laser hair removal involves targeting the pigment in the hair follicles with concentrated light energy. This energy converts to heat, which damages the follicle's structure, inhibiting its ability to produce hair in the future.

Over time, consistent treatment can lead to the weakening of hair follicles, making it challenging for them to regenerate hair. In some cases, they may stop producing hair altogether after sufficient damage has been inflicted. This contrasts with options suggesting that hair follicles are completely destroyed, which is not universally accurate, as some may retain the ability to regrow under certain conditions. Additionally, regrowth aspects vary with treatment parameters, including pulse width, making the assertion regarding the pulse width irrelevant to the general principle of hair loss with regular laser treatments.
