Shedding a small amount of hair daily is perfectly normal. Everybody will shed 50-100 hairs a day as part of their natural hair growth cycle. You hair grows in a constant cycle of growth, shedding, and renewal that repeats continually over your life. Your hairs are cycling, not in unison but asynchronously, so only a small portion (about 0.075%) of your approximately 100 000 hairs are entering the shedding phase at any given time. In all likelihood, what you’re seeing on your pillows, in the shower, or on your hairbrush is just routine shedding that happens day in, day out.
If your hair fall is excessive and you have noticed changes such as thinning of your ponytail, a widening of your part line, or seeing your scalp peeking through under bright lights, then there may be some underlying changes happening to your hair cycle. Your hair and your hair cycle are often a reflection the state of your body as an entire system and can change according to your overall health and wellbeing.
Have you ever wondered why your hair might be falling out more than usual? Read on to learn some common causes – you may be surprised.
Why Is My Hair Falling Out?
Here are some common reasons why your hair might be falling out in greater quantities…
You’ve Had a Baby
About 30-60% of women will experience postpartum hair loss after having a baby.
For most, the post-partum hair shed is a temporary phenomenon that is driven by hormone changes after birth.
During pregnancy your estrogen and progesterone levels soar, particularly from the second trimester, to many times higher than usually seen in the body. Estrogen in particular has a powerful effect on multiple systems in the body including the skin and sebaceous glands, and also on the underlying growth pattern of hair. During pregnancy the excess estrogen encourages the hair to enter and stay in the growth phase, grow faster and shed less, somewhat synchronizing the follicles in their growth.
Following labor and birth, estrogen and other hormone levels fall rapidly to pre-pregnancy levels. In addition, cortisol levels remain high, and in some women thyroid hormones can get out of balance. What this can cause is a rapid synchronous transition of large numbers follicles out of their growth phase and into the resting phase. Couple this with the lack of sleep, potential nutritional stress and the demands of caring for a newborn and a perfect storm for hair changes is in place.
What is important to note is that when the follicles enter the resting phase, they do not fall out immediately, but after a delay of 2-4 months. Scientifically this process is known as telogen effluvium. The silver lining of this is that the fall is actually precipitated in most cases by the emergence of a new hair that has regenerated from stem cells in the scalp.
You’ve Switched Birth Control Pills
Pharmaceutical birth control pills and implants are usually hormones, or combinations of hormones, that work by preventing the release a number of other hormones involved in development of the egg and specific changes in the uterus lining which prevents pregnancy.
Hormones are very potent molecules that that effect the body in profound ways. Many of them can also impact the way hair grows, metabolizes and cycles. After all, it is the sex hormones that cause the sprouting of pubic hair during puberty. Many hormones can affect the hair follicles, changing the way they grow and cycle.
Some women have follicles that are especially sensitive to the impact of hormones altered by birth control and this can result in hair cycle shortening, increased shedding, hair thinning and changes in hair quality. For example, many women notice their hair becomes more brittle and drier. Some women may also notice hair loss when they stop taking a particular type of birth control pill, in this case it is the change or absence of the hormones in the pill that triggers a change in the hair cycle.
The excess hair fall from changing birth control will start to happen 2-3 months after the switch. If you’ve changed your routine in the past few months, or had a new implant inserted, then this could be the underlying contributor to your hair fall, and you may need to look for an alternative.
You’ve Experienced Sudden Weight Loss or Changed Your Diet
Your hair is a reflection of your internal health and wellbeing. Ensuring your body is receiving adequate nutrition and a balanced diet is critical for maintaining healthy hair.
If you are on a strict or restrictive diet and/or have been losing significant weight, your body may not be getting all of the nutrients and energy it needs for healthy hair growth. The body is an amazing machine that intricately conserves and manages energy balance and nutrition. Your body knows that your hair is not essential for maintaining your life, unlike your heart, lungs and brain. So when your body is experiencing nutrient restriction, or isn’t getting the nutrients it is used to, then it will shuttle those nutrients and energy to essential organs and away from the hair. This can result in shortening of the hair cycle, hair follicles prematurely entering into the resting phase and slowing of growth. Excess hair fall may follow.
You’ve Experienced Extreme Emotional Stress
As with diet, stress impacts the way the body shuttles and manages energy and nutrients. High levels of constant stress put the body into a constant fight or flight mode where hair growth is not a critical function and is reduced in favor of other systems. Similarly, with an extreme stress such as a divorce, death of a partner or close family member, or bankruptcy can place the body under pressure, where nutrients supply to the hair follicles is diverted and the hair cycle is prematurely shortened. As with, diet, childbirth and changing medications the hair fall due to stress will usually be delayed by 2-3 months as the follicles rest before falling.
You Have a Medical Condition
Many medical conditions can cause excess hair fall.
Autoimmune diseases such as Alopecia areata and Alopecia totalis cause the body to attack the hair follicles, resulting in complete hair loss in small round patches, or over large areas respectively . If this is happening to you, you may need to see a dermatologist for treatment.
Apart from the medical conditions that directly attack hair, a number of systemic illnesses can result in excess hair fall. Conditions that affect your hormones such as Thyroid conditions (both hyper and hypo thyroid diseases) and polycystic ovaries can influence the hair cycle, leading to cycle shortening and excess hair fall. Medical conditions that affect the absorption of nutrients such as Chron’s disease and IBS can also impact the hair cycle, in a similar manner to dieting and stress.
Your Hair Styles Are Damaging Your Hair
Any hair style that puts pressure on the roots of your hair can have a detrimental impact on your hair cycle and cause excess hair fall through what is known as traction alopecia. The excess pressure can actually damage the small muscle attached to each hair follicle (known as the arrector pili muscle), resulting in a reduced ability for the follicle to cycle and excess hair fall.
If you’re a fan of tight hairstyles, braids or heavy extensions, you should try switching up your style occasionally to give your follicles a rest.
You’ve Inherited It
Genetics can play a large role in your hair health and quality as you age. Some men and women have a genetic predisposition to lose their hair or to significantly thin from a young age. Other people have a predisposition to lose their hair later in life. If you have a family history of thin hair or hair loss, chances are you may also be vulnerable to hair challenges occurring.
We don’t really know the identity of the exact genes that cause hair loss. Hair growth is so complex, as is the signaling that controls the hair cycle, that many genetic factors may be at play for any individual. The best genetic studies of tens of thousands of individuals with hair loss have highlighted that more that 150 genes may be involved. In all studies, firmly sitting in the top 20 of the genes that are involved in hair loss is the hair cycle regulator FGF5 – evolis directly tackles FGF5 to fight hair loss, hair thinning and hair cycle dysfunction
