Weaves will not make your hair healthy
Reliable hair extensions or weaves can offer you style and volume, but it will never be a substitute for unhealthy natural hair - if you have poor hair management, learn how to get it back into shape before you attempt to put on a weave. Chewed or split ends and brittle hair do not make for a good base for extensions, and it might not even blend well, especially when the natural hair weave turns out in better condition than your locks.
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."
Experiment before dyeing
Hair dye doesn't always have the same coloring effect on weaves as it does on your natural hair, so don't just color everything in one go. Instead, try applying on a few strands first and see how the shade turns out - if you're happy with the results, go for it. Don't use chemicals with too much ammonia, though.
If you're looking for the best hair weave to make your locks even more stunning, look no further than salons like Her Hair Company. Choose a salon that has hair that's pretty much the same color as your natural hair to make it blend better.
