These are some ways to show you how to do a lace weave and also a sew-in weave. These techniques can be easily used. As you saw, the lace weave only takes but minutes. However, the sew-in weaves may take a bit longer. It also depends where you go to get it done or if you decide to try putting it in yourself. Personally, I would rather go to the beauty salon. It takes less time for someone else to do it. The question with that is do you want spend money for it and how much will it cost. Remember everyone charges different prices and I don't recommend you get a weave done with someone who doesn't have good credentials. Word of mouth and vision is the best way to find a good hair stylist who can do this type of technique.
If you know how to put in weaves yourself than it may be a better option of you doing your hair because you can save a lot of money. I don't reccomend someone putting in a sew-in by themselves unless the properly know how to do it. The best way to learn is by watching someone else or feel how a person is sewing in your weave so that you have an understanding of what to do. You want your hair to look as natural and well put in as possible.
