Triggers and Types of Telogen Effluvium Hair Loss
There are several types of telogen effluvium. Environmental factors are a type that is apparent within one to two months and can last up to six months. The second is a slow progression. This type lasts longer and is more noticeable due to a persistent trigger. The third is a cycle of thinning and growth, which does not stay dormant for long.
Triggers are anything that shocks the system, including:
- stress;
- diet;
- trauma;
- surgery;
- vaccinations;
- pregnancy; and
- antidepressants.
Lack of iron also may cause the hair follicles to go dormant.
