“Maintain your weave well for longevity
In general, weaves will last about two months before some serious maintenance and styling is needed – keep shampooing it every day, though, as this will keep oil and dirt from your natural hair to stick to and ruin your extensions. You should also keep your hair away from chlorine. If you have to go to a pool, use a swimming cap and make sure that every strand is covered and protected from the water.
Consider using closures
A post in Savagelyyours.com touts the advantages of using lace closure for weaves:
“A closure is for anyone who doesn’t want to leave ANY hair out but still wants a natural look. To me this seems to be the best way to go if you want to protect as much hair as possible. Back to the facts, closures should be the same hair texture as your weave and should blend in with your scalp to produce natural results.””
