Whether it's worth trying is sort of up to you. The steam is normal, tho (especially if you just put oil sheen in it) so no need to panic. Having the hair pressed can make it
more manageable for some people (like me...I don't do hair!!). For my SIL, natural is best b/c she can cornrow like nobody's business.
Somewhere between 8-11 fitting in begins to matter a whole lot more than manageability, KWIM? And if the prevailing style is straight (among the ppl. dd knows) then that's what she'll probably demand.
Lots of people go with the pressing comb to assuage their kids desire to fit in and avoid using relaxers. My mom used to take me in once every couple of weeks to get my hair pressed and with proper care it can last that long. I plan to keep my dd's hair as unprocessed as possible for as long as she'll let me.
We'll see how long that turns out to be.
