How do I achieve thick, straight, and shiny hair? Right now...

#3 was really rhetorical. You can't hate what your hair is and simultaneously wish for it to be moreso.

How do you claim to have ‘poofy’ hair and yet still wish to add volume?

Then, you can go about finding ways to straighten it, otherwise, you'll just hate that too

It you answered ‘curly’ to question #1

You. Have. Curly. Hair.

OK, 3 things

2 things:

what does your hair look like after you wash it?

If you answered ‘dry’ to question #2 this is why your hair looks the way you describe it.

Stop brushing your hair dry and treat it the way curly hair needs to be treated, with moisture, cool water, dignity and respect.

When do you detangle/brush it?

How do I achieve thick, straight, and shiny hair? Right now my hair is very dry, dead, poofy, fine, and a yucky mix between wavy and straight. How do I add volume and make my hair more straight?
