It depends on the type of extension, 100% human hair - very good, others more or less, sewing - in technique , last a long time but hair hygiene is a must. Braiding whether corn row or single patches which more flexibility to do more styles need washing and drying thoroughly. You must follow your cosmetologist recommendation on what product to use, bottom line your scalp must be moisturized every day, not necessarily oil. Ask your cosmetologist about the brand African Pride Spray for Braids, this work for itchy scalps.
