Laser Hair Reduction

Introduction:

• Unwanted hair growth is a common aesthetic problem both in men and women.

• The demand for safe, long-lasting, and effective hair reduction for aesthetic as well as medical indications is on the rise. 

• Laser hair reduction (LHR) is one of the most commonly performed cosmetic procedures in dermatological practice.

• It has gained popularity because it is safe, non-invasive, provides long-term results with minimal discomfort.

How does LHR work?

• Laser Hair Reduction functions on the principle of selective photothermolysis with melanin as its target. This means the melanin in the hair follicle absorbs the laser energy and gets heated up.

• This causes the destruction of the hair and its root.

• Since the target is only melanin, the rest of the skin components are unaffected by the treatment.

Who can get LHR done?

• Women with systemic diseases such as PCOS causing  excessive hair growth over face

• Cosmetic purposes

• Medical indications like pseudofolliculitis barbae, pilonidal sinus, and acne keloidalis nuchae

Who cannot get LHR done?

• Pregnant and lactating women

• Site with active infection

• Patients with keloidal tendency.

• Patients with vitiligo and psoriasis(Risk of Koebnerization)

• We cannot do LHR over tattoo
