Should doing Extreme Vocals hurt your throat and your vocal cords?

This is the two important thing to look out for in case practice does hurt.
Attention screamers and extreme vocalists!
If I offered you to learn how to scream and growl like a professional in 3 months and you could see results on the first 24 hours. Would you take up on my offer?
I offer you to learn how to scream and growl like a professional in 3 months without:
- Practicing hours, a day. You only need to practice 5-10 minutes a day.
- Requiring a rehearsal room or an isolated place. Many of these are quiet practices that won't disturb anyone at home.
- Requiring professional gear to sound good. You only need yourself and your voice.
- Without hurting your vocal cords or throat of course
