Hair Loss Q & A

by Khanh Perrin, MD

What are the different types of hair loss?

Significant hair loss, or alopecia, can appear suddenly or develop gradually as you get older. It can be temporary or permanent, and it can affect just your scalp or your entire body. Some of the different types of hair loss include:

  • Gradual thinning on the top of your head: Most common type in men and women
  • Circular or patchy bald spots: Smooth, coin-shaped bald spots on scalp; skin may become itchy before losing hair
  • Sudden hair loss: May lose handfuls of hair; due to physical or emotional shock
  • Patches spread over scalp: Caused by ringworm

What causes hair loss?

Hair loss develops from a variety of underlying causes including:


This type of hair loss, male-pattern, and female-pattern baldness is the most common. Hereditary baldness follows a predictable pattern -- a receding hairline in men and overall thinning hair in women. It develops when testosterone converts to dihydrotestosterone (DHT), then DHT damages the hair follicle.

Medical conditions and medications

Hormonal changes and imbalances, scalp infections like ringworm, and skin disorders can cause hair loss. Poor nutrition can cause also hair loss, as well as various medications and getting too much vitamin A. The immune system may attack hair follicles, causing sudden hair loss in round patches.


Wearing hair pulled back into a tight ponytail or cornrows causes a type of hair loss called traction alopecia. Hair follicles may become inflamed from hot oil treatments and permanent.

How is hair loss evaluated?

Dr. Perrin conducts advanced tests to determine levels of hormones, including DHT. She also determines whether inflammation or a nutritional deficiency may contribute to your hair loss.  Your treatment plan addresses underlying nutritional or health problems. Dr. Perrin treats hair loss with platelet-rich plasma.

How is hair loss treated with platelet-rich plasma (PRP)?

Platelets are naturally found in your blood, where they’re a source of growth factors that make new tissues grow and promote healing. Platelet-rich plasma contains a higher concentration of platelets than normal blood. It’s made by drawing a small amount of your blood, extracting the platelets, then remixing the platelets in with your plasma (the liquid part of blood).

After Dr. Perrin injects PRP into areas of your scalp affected by hair loss, multiple growth factors begin to stimulate hair follicles and promote new hair growth. PRP can also be used to promote healing and support new follicles if you’ve had a hair transplant.
