When you are very young it can be even moredifficult to deal with hair loss as you could be the only person you know that has it. It doesn’t matter whether it is normal hairloss it can be very hard to deal with.
While hair loss products are something that may be worth looking into, it could be that you do not need them just yet as hair loss can actually occur for a short period of time and it is usually down to one of these reasons:

Starting To Lose Hair
Hormonal changes could be the reason
This can work to speed up the rate in which your hair falls out and regrows meaning that your hair could be falling out faster than it is growing. This can happen for a number of reasons that include pregnancy and even coming off of the pill so do not worry.
Calm down
This is the one that people tend to blame it on even though it is the one method that has not been proved as of yet. The only form of stress that has been linked to hair loss is emotional trauma, other than this it is just presumed that mild strains and worries are linked. Crash dieting can also lead to hair loss but if all of this stops then the hair will actually begin to grow back.
If you are hitting your late 40’s early 50’s and you are a female then loss of hair is actually quite natural. It will not occur in the same way that it happens to men so you will not need to worry about balding as such. The hair will start to thin but it will actually stay there.
However if you are starting to get patchy loss of hair then you certainly need to go and see a doctor as they can five you something that can slow down and even stop this as it may be to do with alopecia, however this can be treated with things like Alopecia Universalis
