Q: At what age does a woman's hair start thinning?
A: Hair loss among women is a common condition, but not universal. A woman won't necessarily start losing her hair at a certain age aside from the normal shedding of hair that occurs daily. Generally 30-40 hairs per day are lost in the natural hair growth cycle.
When and if you will have thinning hair and how thin it will become are determined by genetic and hormonal factors. If you are genetically predisposed to losing your hair, it may start as early as your late teens or early twenties. However, almost 40 percent of women will experience some degree of hair loss by the age of 35.
In this case, the condition is called androgenic alopecia and among women it is seen as a general thinning of the hair all over the head.
Your best bet for determining when and if your hair will start thinning is to look to your mother, aunts, and maternal grandmother. Do any of them have thinning hair? When did theirs start? It's a good bet that if theirs began around a certain age that yours will start around that time. If there's a wide discrepancy in the times their hair started thinning, you will at least have an age range in which to begin watching for the signs.
However, if you are concerned that your hair will begin thinning, you should consult your physician. There are treatment options available to stop hair loss. If you think you are experiencing hair thinning, and there is no history of thinning hair among the women in your family see your doctor immediately.
The problem could be due to illness that was previously undetected, a hormonal imbalance or poor diet, but the sooner you determine the cause, the sooner you can correct the problem and stop the loss. The factors listed above can cause disruptions in the growth cycle of the hair follicles and resolving the issues causing the disruption will allow your hair to return to normal.
