Hair Growth Cycle

Active Growth Phase

(Anagen)

The growing phase lasts 2-6 years and determines the length of hair.

Regression Phase

(Catagen)

Hair stops growing at the stage, which lasts about 2-3 weeks.

Resting Phase

(Telogen)

This stage lasts about 2-3 months. Hair follicle shrinks and detaches from the dermal papilla.

Return to Anagen

Continued shedding of old hair whilst active growth phase starts again.

Causes of Hair Loss

Male Pattern Hair Loss

Androgenic Alopecia

Baldness usually occurs at hairline, top-back of the head.

Seborrheic Hair Loss

Hair thinning occurs symmetrically on both sides of forehead and top of the head.

Hair thinning and miniaturisation begin at both sides of forehead and the crown symmetrically. Excess sebum gathers and accumulates in the excretory ducts of the follicles causing inflammation. Actively growing hair becomes duller, thinner and weaker, causing hair loss.

Alopecia Prematura

Hair line starts to recede and hair loss occurs on both sides of forehead. Hair thinning and itchy scalp are common signs, it may be caused by mental distress.

M-Shaped Hair Loss

The process of receding begins at frontal hairline, gradually affecting the back of head in severe cases.

Diffuse Hair Loss

Stress causes excess production of sebum and oil build-up, as well as scalp muscles to become tense or contract which affects blood circulation.
