• Men & Women observe different patterns and different time of onset of hair loss. In medicine it termed as Male Balding Pattern and Female Balding Pattern
• Female pattern hair loss starts in the late 40’s to 50’s, usually without a recession of the hairline
• In males “genetically sensitive” follicles on the scalp begin to miniaturize in the presence of normal levels of the hormone DHT (dihydrotestosterone). These follicles, found in the frontal hairline and extending into the top and crown of the head, become smaller and produce a hair that is progressively thinner and less pigmented.
• Androgenic alopecia – progressive hair thinning – is the most common form of baldness that occurs in adult males
• Male and female pattern baldness is a result of combination of aging, hormones (androgens/testosterone) and heredity (genetics)
• Female pattern baldness involves a thinning throughout the scalp while the frontal hairline generally remains intact.
• Typical male pattern baldness involves a receding hairline and thinning around the crown with eventual bald spots. This is measured in Norwood scale (I to VII)

Hair Thickness

• Female hair is generally Thinner in comparison to Males
  

Hair and Dandruff

• Dandruff or seborrhoeic dermatitis affects Men more than Women. Some possible causes include hormones, larger oil glands in men leading to oily scalp and hence dandruff
• Many young adults with this condition appear to have a greasy skin, but when the sebum excretion rate from forehead skin was measured in patients with seborrhoeic dermatitis , it was normal in males and significantly reduced in females

Hair Length

• This is obvious one Men in majority tend to have shorter hair in comparison to Women
