How to get straight hair of boys witout straitening?

Perms work or you can use a old method of news papers and water (you wrap hair in news paper and let it dry) I tried it and it worked. Or if your hairs short you can use jell and slick it down to make it appear straight. Im sure if your hair is curly its still nice. Girls love curly heads. If its super curly you should dye the top a golden blonde

Since this is placed in the English category, the corrected sentence would be:
