What are the benefits, risks, and costs of Japanese Hair Straightening? And would I be able to dye m

My hair reaches just past my waist (a little longer than a yard) and it is far too difficult to blow dry or straighten. I've recently considered getting Japanese Hair Straightening and I would like to know about the risks, benefits, and costs.

I would also like to know the risks and costs of dying my hair (a darker color, no bleaching).

Would dying my hair and straightening it soon after damage my hair to a critical point?

Lastly would Japanese Hair straightening effect hair dye in any way?

I would be so grateful to anyone that could help me.

What are the benefits, risks, and costs of Japanese Hair Straightening? And would I be able to dye my hair...?

For hair your length, it'll cost well over a thousand dollars to get the initial straightening, and several hundred every 4 months or so for root retouches. In hair so long, it may cause breakage as it will be more difficult for the stylist to remove from your hair (the straightening chemical I mean).

You can't dye your hair after a "japanese straightening" (usually made by CHI/Farouk Systems) with a permanent color or bleach, you can only use a semi-permanent because it's simply deposits and doesn't open the cuticle of the hair.

If you have permanent color on your hair, a stylist may be wary of offering you a straightening service. I certainly wouldn't attempt it without having you sign a waiver of responsibility.
