Hormonal birth control in the form of pills, injections and patches can too cause hair loss. Thyroid-related hair loss is normally temporary and normal hair growth is restored once the underlying thyroid issue has been treated. Similarly when the thyroid is overactive, like in hyperthyroidism, a condition called Telogen Effluvium can be triggered which also results in hair loss as detailed later on. Therefore, hair is being lost at its normal rate but is not replaced. In cases like hypothyroidism, the body produces too few thyroid hormones so the cells at the bottom of the hair strand are not replaced as efficiently. Thyroid conditions are also known to affect hair growth as the hormones produced by the thyroid affect the rate at which your cells work. This can cause thinning and loss of hair which is typically corrected over time naturally as the body heals and hormones level out.
Throughout pregnancy, estrogen levels are elevated but have a subsequent rapid decline once the baby has been born. Similarly, pregnancy impacts the balance of these hormones. At the same time, the relative level of testosterone becomes higher and women become more sensitive to DHT. Estrogen supports hair growth by increasing the amount of time the hair spends growing so as estrogen declines, so does the length of growth time. When a woman goes through menopause, levels of oestrogen decrease. Menopause is another time where hair loss is more likely to be observed. Women with conditions that lead to higher than normal levels of testosterone, such as Polycystic Ovarian Syndrome (PCOS) are more likely to experience hair loss. DHT links to receptors on the hair follicle making them shrink and therefore decreasing the length of time a hair is spent in the anagen (growth) phase. It is typical for women to have small amounts of testosterone and higher levels of oestrogen, in men, the proportion of these hormones is normally reversed.ĭihydrotestosterone or DHT for short, is produced from testosterone and is thought to be the main culprit responsible for hair loss. One of the main androgens is testosterone. If you’re an avid reader of our blog, you may recall androgens are an important male sex hormone which also play a role in regulating hair growth. Stage III is when the thinning diffuses with the top of the scalp having a see-through appearance.Īndrogenetic Alopecia is caused by an imbalance of androgen hormones. In stage II the scalp starts to show with widening of the mid-part. Stage I begins with thinning on the top of the head, it’s typically easy to cover with certain hair styling. Health professionals use the Ludwig scale to classify the female loss of hair: In women, this type of hair loss is more defined by a gradual thinning of the hair that starts from the hair parting. In men it’s recognised for causing an M shaped hairline, more commonly referred to as a receding hairline. Hair loss in women can occur for many different reasons:Īndrogenetic Alopecia is the main type of hormonal hair loss experienced by both men and women. For some women, hair loss is short term but for others it can be a long-going and highly worrying time. Have you ever found yourself noticing more hair than normal clogging up the shower drain, clinging to the back of your jumper, or falling onto your pillow? Rest assured you are not alone, Harvard Medical School suggests about 33% of women experience excessive hair loss at some point in their lives. Today we want to talk about losing noticeable amounts of hair from ages as early as your 20’s. The average person loses somewhere between 50-150 pieces of hair a day. Why does our hair fall out? It’s fair to expect as we get older our hair will naturally begin to thin. The old hair falls out and the new hair continues to grow. A new hair begins the anagen phase in the background.

The follicle shrinks allowing it to move closer to the skin surface.įinally, the follicle stops moving and rests. In this phase, the hair follicle is detached from the blood supply that has been providing nourishment and fuel for the hair to grow. This is when the hair is growing - different people will have varying lengths of time their hair remains in this stage depending on genetics, or age. It’s growth is defined by four main phases: Hair is made up of a protein called keratin.
Hair grows almost everywhere on our bodies, apart from the soles of our feet, lips, palms of our hands, belly buttons, on scar tissue and some parts of the genitals. There is a huge variety of normal hair growth amongst different women, and genetics.
Before we jump into understanding how unwanted hair loss occurs, we first need to appreciate the natural cycle in which a hair grows.
