Telogen Effluvium — An occurrence in which the number of hair follicles producing hair drops significantly for any reason during the resting or telogen phase which results in shedding.
- Can become acute or chronic. Hair loss may not be consistent and even all around.
- There will not be complete hair loss but there will be hair thinning.
- Causes: stress, poor diet, change in prescription drugs, may occur as part of some other underlying disease or symptom such as Alopecia Areata.
- Development of TE: environment factor shocks the hair follicles into resting state, the hair follicles may just go into resting state and remain for a a prolonged amount of time or hair follicles may go through short growth cycles which results in persistent shedding and thin hair.
- Short term TE may be caused by a trigger so the best way is for the hair follicles to naturally correct themselves
- Long-term TE treatment varies on the causal factor which may be corrected. Otherwise, can be prescribed a hair growth stimulator by a dermatologist such as Minoxidil
- Chronic TE is common and typically affects woman in their 30-60’s who had thick hair in their teens and twenties.
