Natural hair retains length the easiest, because it is stronger. Chemical relaxers weaken the strands. However, whether you are relaxed or natural, there are some basic things you can do to promote length retention. Remember, your hair is ALWAYS growing at a rate of 1/2 inch per month, on average. What you have to do to SEE the growth, is protect the ends of your hair from breakage.
Here is a nice regimen to follow:
Shampoo weekly with a sulfate-free shampoo
Use a moisturizing rinse out conditioner
Usa a leave-in conditioner
Use the least amount of heat possible to style. Try twist sets or roller sets instead of curling irons and flat irons. Air dry instead of sitting under a dryer when possible.
Use a moisturizer every day or two
Wear styles that keep your ends tucked under to keep them from rubbing against your clothing, such as buns. Wear your hair "loose" only for special occasions until you feel your hair is healthy enough to endure wearing it out/down more often.
Sleep on a satin pillowcase or wear a satin scarf or bonnet each night.
If you follow these guidelines, you should see 6 inches of growth per year, on average.
