While thinning of the hair is to be expected during cancer treatment as was my wife’s case, if you think your hair is thinning, not to the extent of bald patches appearing, it is important that you check that this is actually happening and not just normal shedding. It is normal to lose 50–100 hairs a day – which can be quite daunting when seen collectively on the comb or brush. It’s unusual, but sometimes when your down or depressed, the thinning of the hair can be in the mind, as a symptom of depression, just because of seeing more hairs than expected or normally paid attention to!
Thinning of hair all over the scalp (rather than patchy baldness) can be due to various causes. In the case of mental or physical stress, it often occurs 2–3 months after the event. This is because at the time of the stress many follicles enter telogen (the resting phase) prematurely, and are then shed together at the end of telogen a few months later. In this situation, the hair loss usually recovers completely.
Again, my wife was on anticancer drugs, blood thinning drugs (warfarin) and just a bit depressed with the whole experience – no surprise that her hair remains thin and now the doctor is treating her with shampoo at the moment to relieve possible eczema or psoriasis – and he hasn’t ruled out that her thyroid has been affected at some point in the treatment over the year.
If you believe your hair is thinning, do not assume it is due to stress. See your family doctor, who will be able to rule out the common causes (such as thyroid deficiency and iron deficiency). Many drugs – not just those listed below – can cause hair loss, and the doctor will be able to check if this is a possibility. There may be several months’ delay between starting the medication and the hair loss being noticeable (true from experience).
Some skin disorders, such as eczema or psoriasis of the scalp, can cause thinning of the hair. Usually the hair grows again once the skin problem is treated.
Some drugs that may cause hair thinning
Often no cause can be found. In some of these cases the hair will recover in time, but in others it remains thin.
It is important to keep thinning hair as healthy as possible. If there is no curable cause and the thinning is distressing, it may be worth trying Regaine. Bear in mind that Regaine will take several months to show any effect, and works in only a proportion of cases.
