I am 24 years old. I have a thin hair. There is no volume in in my hair & my hair falls a lot. Any solutions for this?

Shave it all off, go to the gym, and get super buff.

I have fine hair as well.  The best thing was for me to get a shorter hair cut that flattered my face and added volume.  Taking care of your care is important--not too much heat, using a clarifying shampoo, not letting it get too oily, and not weighing it down with heavy products.  Also be careful of breakage of hair by wearing tighter hair styles.

Buy some hats.

1.Using too much heat for styling/straighten your hairs cause the falling.

2.Using too much products such as creams,sprays ect . .cause the falling.

3.Using too much ties/clips also cause the falling.

4.You need choose your shampoo by the condition of your hair, oily,dry ect . . Then considering medical conditions, make sure if you  have all the vitamins that your hair would need to keep the flow up. Then consider it all for your shampoo usage. Shampoos divide by age,skin type, hair type & medical conditions.

5.Wash your hairs properly specially when you use any product over your hair, the best routine would be  once after you wake up & once before you sleep or at least once each day because even if you don't use anything chemical, yet there's dust,smokes & so many materials around that effect your hairs & they need to be washed properly.

6.Make sure you wash your hair very well with attention, if any foams stay on your scalp, even so little, they turn into white masses, the white masses will make the core of your hair weak & will cause the falling.

7.Massage your scalp everyday for around two minute, specially when you showering.

8.Brush your hair properly (it's just another way of massaging as well)

9.Wash your hairbrush daily.

10.Make sure you using an appropriate hairbrush. (the materials of the hairbrush are  important (plastic, iron ect . . Following your hair's condition) the style & form of the hairbrush also must  be suit for your hairs as well, the cleanness of the hair brush)

11.Check your nutrition.

12.If you recently moved from a place to another which would be a different geographical spot, that would be the cause which in that case, it will be fine cause your body will get use to the place eventually, however,some extra vitamin/health care might help more. (when it be the case)

13.Make sure if there's any infection (you can check that one with a doctor) the infection can be caused by different thing such as just reckless touches, inappropriate products or even crossing a place that someone didn't followed a good hygiene there, dirtiness of the weather & air ect . .

14.Make sure you are understanding hair loss definition as well, sometimes people get so obsess with their hair loss while they forgot human's hair falls everyday in a grow-regrow cycle.
