These are a few tips that I found very useful for me in terms of prepping for a braid or sew-in installation as well as care for the duration of having a long term protective style.
1.
Wait 2 weeks after you have received a chemical treatment before you install any braids or a sew-in. When you apply a chemical treatment you are weakening your hair strands and immediately doing an install will cause extreme breakage or hair loss.
2.
Do a good protein treatment and moisturizing deep conditioning treatment 1-2 days before your install. This will put that protein and moisture balance into your hair strands prior to the installation.
3.
NEVER BRAID BREAKING OR DAMAGED HAIR! Too many times people think the solution to damaged hair is hiding it under braids or a sew-in. This is a recipe for disaster when you take down your install. Correct any damage before putting braids or sew-ins into your hair by conditioning and trimming any dead ends.
4.
Don't braid your hair too tightly. Braiding hair too tightly will cause hair loss along your edges and nape. Ensure that the braids are secure without excess pull.
5.
Alternate between a protein and moisture spray. Again, keeping the protein and moisture balance is imperative even though your hair is hidden. Spritz your hair 4 days with a moisturizing spray and 1 day with a protein spray.
6.
Lightly seal hair with an oil. This is the same as moisturizing and sealing your hair. Find an oil that will light enough not to create build up.
7.
Oil scalp as needed...not daily. You don't want to create build up on your scalp because you won't be washing your hair as often since it is under braids.
8.
Shampoo and condition every 7-10 days. Once a week is enough to shampoo/condition your hair. Any more than that will of course create frizz. If you choose to still deep condition it is recommended that you dilute the products with water to help with the process of rinsing all of the product out.
9.
Cover hair with a satin bonnet. Treat your installs like you would treat your real hair. You wouldn't go to bed with a scarf so why would you go to bed without one since you have an install?
Hopefully these tips will help you to retain as much length as possible with your installs!
