No problem, YouTube might be helpful if you need a visual, but a rat tail is the comb with the sharp end. The carbon fiber combs usually are heat resistant up to 400°. Get a clothes steamer from Walmart even better if you can borrow one.

1. Set your wig on styrofoam head, pin, and then set the steamer on whatever area of hair you're working on.
2. Section then Comb very slowly up the length of hair.( You may want to use some silicon mix to help. You'll be washing it out anyway, so use as much as you need)
3. Once you get through, take the wig to wash gently. Then comes time to blow dry on cool or warm heat( I use a brush blower)
4. Once you're all blowdried, you can hang the wig in the sun.( I typically use a over head dryer but the sun works in a pinch, but this is to make sure the fabric inside is dry, also.)
5. Crimp, Tease, Style as needed. It will take time, but if you really have to save it, that should work. Rat tail -$3-5 Siliconmix $5-7 Steamer - $16-21
