That doesn't work for everyone. Blow drying makes my hair impossible! It gets hard and flyaway and looks dry and brittle and the ends look awful, and no amount of pressing or product can fix it. It's worth a shot though, because it works really well for some folk. For me, much better than blowdrying is to try to get hair as straight as possible when really wet with a fine toothed comb and tension, then wrap or band or bun it till it dries and tie a satin scarf over it (even if that takes a day or two - you can speed it up with a hooded drier) and then have it pressed after it is already somewhat stretched that way.
Get used to me. Black, confident, cocky; my name, not yours; my religion, not yours; my goals, my own; get used to me. -Muhammad Ali
