Hair extension crimping opposed to glue?

My friend and I are wanting to apply hair extensions. We want to purchase everything for Sally's Beauty Supply

But I am not sure if I want to crimp in kind or the glue in...

Which one works/holds in better?

Any other suggestions? besides clip ins! :-P

Thank You!!!!!

Hair extension crimping opposed to glue?

I have liked the crimping method the best. I have found that it damages the hair less and is quicker.

I order occasionally from Sally's but have found Donna Bella Milan www.donnabellahair.com to be much better. Their quality of hair is higher and their price is lower.

Give them a try!
