There is no real miracle that can help you grow your hair thicker and/or longer. You can help by using really good conditioners and deep conditioning treatments, to help your hair grown longer and stay healthy. Frequent trims (about 1/4 of an inch every 3-4 weeks) will also help keep you hair healthy, which you will want if you are growing it long. Don't do too much heat styling (blow drying, curling, etc.). For the thickness, maybe try products like Nioxin. Or before styling after your shower, use KMS's Volume/Thickening cream products. They seem to work well. The main thing about it is keeping your hair healthy and free of split ends and dryness. Use good conditioning products if you must use heat on your hair on a regular basis.
Here is more advice:
It will not make your hair thicker or thinner. it will only do that if you over process your hair.
Shaving does not "make your hair grow back thicker".
No it just make your hair shorter. :D
If you got your hair cut in layers it would seem thicker.
Nothing that you can put on from the outside will make your hair grow thicker. (With the possible exception of Minoxidil.)
add more hair to your bangs :)
Some do make it seem like your hair is getting thicker,but really it makes your hair more fuller and teased.Some ointments can help the scalp.
yes
well if you are stressed your hair will fall out
Use mouse , that will thicken you're hair . ^Hi, I am a different person to the person above^ There is no way of making your hair thicker. If you are born that way, there is no way to make it thicker. You can, however, use a "build it up" shampoo/ conditioner, to make it LOOK bigger. Hope I helped. :)
To make your hair grow longer you could try oiling it and giving it a trim- to make it get thicker then you'd have to try not washing it for a while and let natural grease into your hair to make it healthy [i think =) ]
Do not dye your hair. Take care of it and use good shampoo.
