Our hair normally goes through a "resting phase." It happens about every three years and lasts about three months before our hair starts to grow again. During this resting phase, more hairs than usual fall out, and our hair looks thinner. This process is called "telogen effluvium." It can be brought on quicker by stress, starting earlier and lasting longer in the natural cycle of hair growth and rest.
These factors can also cause hair thinning:
- It could be inherited
- Certain medications, including many antidepressants.
- Hormone changes after childbirth or trauma such as surgeries (usually about 6 months after)
- Scalp problems such as psoriasis or seborrheic dermatitis
- Physical stress on hair roots, such as braiding hair or pulling it back in a pony tail
- Certain medical conditions, such as thyroid problems
Mioxidil (Rogaine) helps some people. It's an over-the-counter medication that you apply to your scalp. But results are mixed. For men, oral finasteride (Propecia) can be helpful. The pharmaceutical community is working on more effective hair growth products as we speak.
There is no "magic bullet" to jump start hair growth. But taking good care of your body and keeping up a healthy and hopeful attitude can help.
