Sure you can, but I guarantee you, your hair will not be as soft and wavy (will be much worst) as TS's.
Let me fill you in about what to expect when it comes to perming hair, then you decide if you still want one or not.
Going to the salon is not like buying clothes, there are risks and there's no money back guarantee.
What you can NOT do when you just got a perm:
1. Don't be out in the sun, even humid weather can fry your hair, that would be like sitting in a helmet hair dryer at the salon for 20 mins.
2. Don't straighten your perm at anytime!
3. No swimming, chlorine will discolor & damage your perm.
4. Don't go using curling iron.
Do use a diffuser to briefly dry your hair, or low heat.
Do use gel to scrunch, like Samy, after you towel dry. Toussle the hair, and finger comb to style.
Use conditioner ANY conditioner formulated for permed or damaged hair.
Set your hair using plastic curlers, it will tame the curls, make it softer, silkier and shinier. It is less damaging to hair. Blow-dry, remove & finger comb.
You don't need to wash it everyday. In the morning, spray with water/conditioner, scrunch to wake the curls up & finger comb & you're good to go.
Since you've never had it permed before, there's no guaranteed it will be permed 100%, but let the salon know it didn't take, she'll re-perm no charge.
If you have thin hair, I do not suggest you getting a perm. You can set your hair with plastic curlers, to STILL make your hair look thicker, shinier, silkier, bouncier, softer & look fuller.
Since your hair is straight, after you towel dry, braid your hair in several small sections. The smaller the braids and more sections, the tighter the curls. The bigger the sections the larger the braids, the looser the curls. Should last for days.
Example from YA HAIR with a bad perm:
my hair 24 hours ago looked super silky smooth but now it looks like a dry mop.
i need to fix this right away. Is it possible for me to get a straightening treatment like those japanese straightening treatments after my perm? I can't live my life looking like this help! please, i'm on the verge of tears
Once you get the perm, you just can't wash them, like shampoo or conditioner and your hair is normal again. It needs frequent cutting to get them all off, to allow new growth to take over.
One method to tame the curls, add body, bouncier, thicker, softer & shinier hair is to set your hair with plastic curlers after you towel dry, you'll end up with uniform balance of curls. Blow dry briefly while curling them in curlers. Take them out, and finger comb to style. Used by the best hair color models, and the fashion industry, like Victoria Secret Fashion Show Dec. 2009, America's Next Top Models, EXPRESS, Dancing with the Stars . . . . and continued to be used today where salons care about pampering your hair. Even Oprah uses them! When you see hair on TV a hair color commercial, they're not done by curling or straightening tools. Hair that shines like that and feels like hair, not hay, has to be done by the best hair tools available w/out damaging to the hair. When you take the curlers out, finger comb to style or lightly brush. Tousle the hair up. or shake your hair. You can use large, medium or small curlers, that depends on the length of your hair.
I know hair. I have over 4 decades of hair know-how. I have silky, shiny, soft, smooth very healthy hair down to my knees. Previously damaged by perming & dyeing in the 80's & 90's. I've known people in their 30's whose hair stopped growing from ironing their hair in the 70's.
