Hair loss can be due to a number of factors including:

  1. Genetic factors - women may start noticing thinning where they tend to part their hair and hairline, whereas men may start losing hair from the crown and the temple.
  2. Stress - hair loss may be due to a stressful event. Most often hair loss is not immediate and may first show 3 to 6 months later.
  3. Nutrition - diet can play a significant role in hair growth. Hair grows from the scalp thanks to a rich environment of vitamins and nutrients obtained through what we eat.
  4. Hormonal imbalance - hair thinning can due to health concerns such as thyroid conditions, hormonal changes especially increases in dihydrotestosterone (DHT) which affects the male hair follicle, and some medications for blood pressure, diabetes, heart disease, and acne.

What we test

Hormonal Changes - male

In men, DHT affects the hair follicles making them smaller, producing hair that is shorter in length. Eventually the follicles shrink completely and hair is no longer produced.

This blood test measures:

Dihydrotestosterone is a tissue metabolite of testosterone. DHT has the ability to bind to sex hormone binding globulin (SHBG) more than three times higher than testosterone. Elevated concentrations of DHT can be observed in men with male pattern baldness or Klinefelter's syndrome.

Nutritional Markers

Our diet can play a significant role in the growth of healthy hair. It is important to remember that a healthy scalp supports healthy hair. The hair grows from the scalp thanks to a rich environment of vitamins and nutrients that are obtained through what we eat. For this reason, it is important to eat a healthy balanced diet.

Thyroid Function

Your thyroid gland produces hormones that regulate growth and energy expenditure. Thyroid disorders are quite common, and many people don’t have any symptoms at all. This thyroid test screens for the thyroid hormones that play a key role in regulating the body’s metabolism.

This thyroid test measures:

Communicates with the thyroid gland to produce T3 and T4 which regulate metabolic functions. High TSH thyroid test levels indicates an underactive thyroid, and low levels an overactive thyroid.

Measures the thyroxine that is freely circulating and able to regulate metabolism. High FT4 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.

Measures the triiodothyronine that is freely circulating. High FT3 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.
