Unexpected episodes of hair loss in women, whether sudden or gradual is more common these days than it's ever been.
This has been written by women for women. We are women who have also suffered from varying degrees of female hair loss due to unexpected factors so we have a lot to share with you. We have outlined the 10 most common causes of hair loss in women here and you will also find some great solutions.
Hair naturally thins out as we age and this often happens gradually. However, noticeable or sudden hair loss occurs most of all at two specific times in a woman's life - during/following menopause and following pregnancy. Read more about these specific causes at the links below:

With about 1 in 4 women suffering hair loss there are clearly other causes too. So here we list some of the most common causes of hair loss in women and some suggested solutions.
#1 Hair Loss Cause in Women - Age and Menopause
Although a change in hormone levels can be responsible for thinning hair during and after menopause, it is worth noting that following menopause, hair can be thinning out in one of three ways:
First, the natural growth cycle may be interrupted and/or slowed resulting in diffuse hair loss. This is generally caused by a change in hormone levels.
Secondly as we age, our hair follicles can get narrower and this gives the appearance of less hair, when in fact you may have the same number of hairs, they are just much finer. This is especially the noticeable for women who had very thick dark colored hair.
And lastly, low estrogen is also known to make hair dry and therefore more susceptible to breakage.
#2 Hair Loss Cause in Women - Low Iron and B12
Feeling tired as well as noticing some hair loss? In that case, the cause of your hair loss could be low iron and/or vitamin B12. Think this is possible? Read more about low iron and hair loss here. The good news is that once the proper levels are restored with the help of supplements and/or diet changes, your hair loss may subside. Head to your doctor for a blood test to find out if this is your issue.
#3 Hair Loss Cause in Women - childbirth
During pregnancy, a lot of women will actually experience thicker hair due to the peak in estrogen levels. This ceases, however, once your baby is born so it is common to experience hair loss after childbirth. Just sit tight, focus on your new bub and your hair should return to normal.

#4 Polycystic Ovary Syndrome (PCOS)
Although extra hair growth on the body is common in women with PCOS, in a cruel twist of fate the hormonal imbalances can also cause hair loss in women. So, more hair where you don’t want it and less hair where you do. Unfair. To confirm this diagnosis you should see your GP. In the meantime, if you are conscious of a visible scalp, shake in a concealer like Boost N Blend™ and you will BOOST hair at the roots instantly.
If you’re taking any regular medications, you may not be in 100% tip top physical condition. Many illnesses or just being unwell can cause hair loss in some women and sometimes it can be the medication itself. It’s important not to overlook any medications you may have been on long term (I’m looking at you, contraceptives) where you have altered your dosage or recently stopped taking them altogether.
#6 Extreme Weight Changes
Putting yourself on a restrictive diet can mean you miss out on some essential nutrients and that can cause thinning hair in women. Likewise, gaining a significant amount of weight quickly can also put your body out of whack and mean that you experience thinning hair. So stay away from the fad diets if you don’t want to lose more than weight.
Because hair is viewed by the body as non-essential, it is often the first thing the body stops assigning resources to, meaning it can begin to fall. Hair loss is a common symptom of a lot of illnesses e.g. autoimmune diseases, but what you may be surprised to learn is that hair loss in women can be caused by acute illnesses like gastro. These short but intense illnesses can put enough temporary stress on the body which can lead to hair loss in women usually around three months later. The good news is that this type of hair loss can usually right itself without intervention.
#8 Over styling
It’s probably not much of a surprise that heated styling products like straighteners, curling irons and hair dryers can cause hair loss in women, but did you know that your hairspray, gel or even the type of shampoo you use could also be causing your thinning hair? Be careful not to overuse styling products or opt for natural products. Whilst you’re at it, be careful with your poor head! Simple things like tight ponytails and harsh brushing can also cause hair loss.
#9 Hair Loss Cause for Women - Gut Issues
It should be no surprise that a healthy gut is needed for an overall health body. It's all very well to be careful what you eat and to have a generally good diet, but if your gut is not healthy (eg IBS) and you are not able to absorb the nutrients in your food then your hair follicles are not getting fed.
What you eat goes through your intestinal system during which time your gut wall absorbs all the goodness out of your food, leaving just the waste.
If you have any kind of gut issue like chronic diarrhoea, IBS or if you are taking a medication that is affecting your gut health (eg Metformin can cause malabsorption, antiobiotics can also mess with gut health) then it is worthwhile seeing your doctor about it. If your hair loss cause is an unhealthy gut, the good news is, once fixed hair loss can be reversed.
#10 Hair Loss Cause for women - An unhealthy scalp
An unhealthy scalp can cause inflammation which then makes it difficult for hair to grow. Some of the skin conditions that can lead to hair loss include seborrheic dermatitis (dandruff), psoriasis, and fungal infections such as ringworm. If you are a gardener, think of your scalp like the soil you put your plants in. Great soil = healthy plants. When the soil is dry, partched and lacking in nutrients, then nothing can grow. Our scalp is the same. Be careful with super hot water, use chemical free shampoos and conditioners like the Carelli range and try to avoid getting your scalp sunburnt.
Hair loss in women can become your Achilles heel. For many women one bout of hair loss that rights itself following pregnancy or an illness reoccurs later when the same or another trigger hits.
If you are suffering sudden hair loss ask yourself what you were doing three months ago. Since hair goes through a three month cycle it is often the case that it was three months ago when your body was stressed that the damage was done.
Whilst some of these causes for hair loss in women may have their own solutions (e.g. changing the medications that are causing your hair loss), there is no absolute cure for hair loss in women available today.
