Hi Gals,
Just pop into any korean hair salon and ask for a digital perm..it is not harsh and lasts about 3-4 months..big bouncy curls that looks so natural. costs about US$130. depending on length of hair. They have fancy equipment..they roll your hair in special rods which is attached to a electical 'spaceship' above your head so negative ions are discharged into the rods and it curls..takes about 2 hours for the whole process includng shampoo, styling, cutting etc.
similar, if you want to straighten your hair, ask for the straight perm using the latest ion tech..good for the hair..
Cheers,
