Nekoshema, and Nano.Zasha made valid points. There isn't a spell that i think would do that.
Talk to a doctor, get hair products that suite your wants, and needs. If you want lucious hair, use Herbal essences with conditioner, or any shampoo for that matter. Wash hair, leave on for 2-3 minutes, rinse and do the same with conditioner. After rinse with cold water...this gives shine, and volume.
Anyways if you find a spell that works, then do it.
Since on chat, you may have gotten gagged. But you said you read too fast, did you agree to the rules? If you fail, you can take a new test in 2:30 hours.
Good luck, message me for more help!
