Hair loss after weight loss surgery
It is a common type of alopecia where there is widespread thinning of the hair, rather than specific bald patches. Your hair may feel thinner, but you're unlikely to lose it all and your other body hair isn't usually affected. It can be caused by a number of factors and the body reacting to:
It can occur after any weight loss surgery but tends to be more likely when your weight loss is rapid, which is more often the case with a gastric bypass. Hair loss will usually start at 6 months after the operation, you will notice when you wash or brush your hair that it is coming out in clumps which can be very upsetting. In most cases of telogen effluvium, your hair will stop falling out and start to grow back within six months.
It is important to remember that it will grow back and it isn’t like going bald. In fact there will be a point when you see new growth. It is also very variable between individuals with some people experiencing none and others a substantial amount.
Minoxidil is available as a lotion you rub on your scalp every day. It's available from pharmacies without a prescription. It's not clear how minoxidil works, but evidence suggests it can cause hair regrowth in some men
Minoxidil lotion may help hair grow in around one in four women who use it, and it may slow or stop hair loss in other women. In general, women respond better to minoxidil than men. As with men, you need to use minoxidil for several months to see any effect.
So the message is although hair loss after weight loss surgery is distressing it isnt permanent, and with time and a slowing down of weight loss it will regrow. Try to eat a balance of foods, take your supplements and also drink plenty of fluids
