What should I do? I have a very less density of hair on my scalp, although I do not have a hair fall problem.

Less density if fine. From birth if your hair is not thick, looks thin, straight and hair is having less volume. It’s fine.

Usually curly hair people always look they have more hair.
People with straight hair, even slight hair fall we feel they have so much hairfall.

So if possible see how much hairfall you are getting every day.
Do some gentle combing, never be harsh with hair. Remove all the frizzles in hair and count how much hairfall you have.

If it’s 100–150. It’s fine. It’s just that you are having less hair. Don’t worry. Not everyone has hairline till their temples.

If it’s 150–200 hair fall once in a while it’s fine.

Anything above 200 regularly, say one week, you are slowing starting to lose hair. In fact, in some cases it might have already started.

So you might now have less hair and you think you are having less hair fall.

Don’t worry Confirm yourself, just roughly count fast, how much hairfall you are having for next 7 days or 15 days to be exact.

You will know the truth.

To increase volume of hair, can’t do much. It’s like some people have thick beard and moustache. Some always look young. So as long its not hairfall don’t worry that you have hair that looks less on your head.

Focus on the problem which is hairfall or not, there is only so much we can do to improve appearance.

Even, if i suggest to increase the density of hair, it is not a guarantee it will work.

Plus the time, effort, money is not worth it. Finally, even if you did achieve good hair density it will be tough to maintain over a long period of time.

As i said, my answers to not give miracle cure. It is just to tell you the truth.
I don’t want people wasting their time worrying about hair too much.

You are hungry, what will you do? Do the needful.
Yes, looks are important. So do what you can do with clarity of where this will end. Don’t bother too much is all i can say.
