my natural hair has been growing out lately and it makes an obvious differences. As my natural hair are straight but the unit is of body wave... I look very ugly now. Also problem with hair color and length blending, I wonder if any of you guys dealing with these issues and how?

How often do you get your hair cut?

You have to get it cut once a month, or it's not going to look right.

Why don't you order with straight hair rather than bodywave?

For light touch-ups that you can do yourself use either a razor comb and/or blending shears. Both are great for when you need a just a little snipped off. Debbie sells both items--go to 'glues and tapes' and you'll be linked to her site for ordering.

just went to some local stylist, told him that i have highlighted my hair on top so it look a bit different, and ask him please dont cut it... i chose a bald guy stylist i think he knows whats going on.
very fine skills and he charged less than $20 for the service... look amazing again once the side and back are trimmed down , blending is not a problem again :-)
