Hair thinning is a very common condition seen in both men and women. There are many different causes of hair thinning or hair loss.
What are some of the causes of hair thinning or loss?
Nutritional deficiencies is a common cause of hair thinning, especially in women. Low iron is one of the most common deficiencies that leads to hair thinning.
Hormones is another reason why your hair may be thinning. Androgenic alopecia, also known as male pattern hair loss, is very common in men. It has to do with a hormone called DHT (dihydrotestosterone). DHT is converted from Testosterone via an enzyme 5-alpha reductase.
Androgenic alopecia may occur in woman due to ovarian cysts, the use of birth control pills, pregnancy, and menopause. It is common in conditions such as polycystic ovary syndrome (PCOS) where there is a reduction in progesterone and an increase in circulating androgens. It also begins in woman around perimenopause and menopause when female hormones begin to decline along with serum hormone binding globulin (SHBG). As the name implies, SHBG binds hormones, such as testosterone, making them less bioavailable. So while total testosterone may not be increasing during menopause, the amount available to reach target cells does increase, thus allowing DHT to rise and hair to thin.
Thyroid and stress hormones may also impact hair health. After a period of high stress, some people may start to notice increased hair shedding and a reduction in the growth of new hair. This condition called telogen effluvium, often begins 3-6 moths after a stressful event. Thankfully, this type of hair loss is reversible.
There are treatment options to help restore your hair health. The starting place is to determine the cause of hair loss and begin an appropriate treatment plan. Basic blood work that includes a CBC with differential, and iron panel or ferritin, thyroid tests, basic hormones including DHEA and inflammatory markers is a great starting place. Combine these tests with good history taking and the cause of hair loss may be determined. In some cases, your Naturopathic Doctor may recommend a Food allergy test , an adrenal panel or a complete hormone panel .
Once we have determined a cause, a treatment plan will be developed. This may involve balancing hormones, supplements to support hair growth, and managing stress.

Q and A: All About Hair
What is hair made of?
Hair is primarily made up of a sulfur rich protein called Keratin. Keratin is made from a combination of amino acids and micronutrient cofactors. Important nutrients for healthy hair formation include :Sulphur, Biotin, Iron, Copper, Lysine, Zinc, Manganese, Lysine, Proline, Vitamin D, and B vitamins.
How Does Hair Grow?
Hair grows from the base of the follicle, known as the bulb. The Bulb is supplied with nutrients from the body via tiny blood vessels. The cells of the bulb divide rapidly which results in 0.3 mm to 0.4mm of hair growth above the scalp, per day. The bulb and hair follicle are susceptible to subtle changes in their environment. Hormonal changes, chemicals, stress, and poor nutrition will significantly impact the rate of division and quality of cells being produced.
Hair growth follows three stages: anagen, catagen, and telogen. At any given time, a random number of hairs will be in one of three stages of growth and shedding.
- ⦁ Anagen is the active growth phase. The cells in the root of the hair are dividing rapidly. A new hair is formed and pushes the old hair, or the hair that has stopped growing, up and out. During this phase the hair grows approximately 1 cm a month. Scalp hair stays in this active phase of growth for two to six years. About 85% of the hairs are in the anagen phase at any given time. The longer the hair stays in the anagen phase, the longer the hair can grow. Individuals that have difficulty growing their hair long, tend to have a shorter anagen phase.
- ⦁ Catagen phase is a transitional stage and about 3% of all hairs are in this phase at any time. This phase lasts for about two to three weeks. Signals are sent out to stop growth. The hair follicle shrinks and blood flow is diminished. The follicle detaches from the bulb, allowing the bulb to rest.
- ⦁ Telogen is the resting phase and usually accounts for 10-15% of all head hairs. This phase lasts for about 3 months for hairs on the scalp and longer for hairs on the eyebrow, eyelash, arm, and leg. During this phase, the hair bulb is completely at rest and the club hair is completely formed. This phase is known as the “shedding phase”. The hair, separated from the base and nutrient supply will eventually be pushed out by the newly forming follicle and hair beneath it.
How do Hormones Affect Hair?
Estrogen: can stimulate new hair growth and extend the anagen phase. Hair thinning in women generally becomes noticeable around menopause and in conditions like PCOS where female hormones are lower and androgens elevated.
Progesterone: This hormone helps keep your hair thick and full by counteracting, or inhibiting, the effects of 5-alpha reductase, which converts testosterone to dihydrotestosterone (DHT). DHT is a strong testosterone and is responsible for hair miniaturiziation seen in androgenetic hair thinning.
Dihydrostetosterone (DHT): (DHT): This hormone is the main culprit of hair thinning and loss. Hair loss is an inevitable part of aging. Hormonal imbalances, certain health conditions, and some medications can also contribute to thinning hair.
What Causes Hair Loss in Men and Women?
While men are more likely to lose hair than women, many females also struggle with premature hair loss. Reasons can range from nutrient deficiencies to more serious underlying health conditions. Treatment primarily depends on the cause of the hair loss and its severity. Most of the time treating the underlying cause can curb hair loss. For example, physical stress in the form of surgery, trauma, or illness can cause temporary hair loss. Once the stress has ceased, the hair loss will typically come to a halt.
Hormonal problems, such as imbalances, are a fairly common cause of hair loss. In some cases such as pregnancy, the hair loss is temporary until the hormones level out following birth. In other causes, chronic hormone problems can cause continued hair loss. Elevated androgens, insulin issues, and fluctuating thyroid levels can also lead to hair loss. If you think that your hair loss is associated with hormone problems, undergo testing to determine the primary cause.
