On your head you'll have around 90,000 to 150,000 strands , which means on average we grow about 60 meters of hair a day .
Each follicle produces hair for between two and four years , followed by a period of two to six months during which the hair becomes loose and is pushed out as the follicle commences production of new hair . In this ways , 50 to 100 hairs a day are lose and hair length is normally limited to 45cm to 60cm . A record hair length , however was more than two meters .

Each hair is supplied with its own conditioning agent called sebum . This is produced in the sebaceous gland , situated in the side wall of each follicle . This sebum is necessary to maintain the normal condition of the skin and hair , reducing damage by preventing loss of moisture . The amount produced varies from person to person and can be influenced by factors such as diet , nervous tension , scalp massage , age and ill health . The sebaceous glands are particularly active during adolescence .
