Interlocking is a method of locking hair instantly. Your locs may be thin at first but they will fill out as they mature. This can be a lengthy process therefore please block the day of your appointment. Make sure you bring a snack, something to drink, lunch, a blanket, anything you may need to make your time in my chair more comfortable, Shampoo and conditioning included. It is recommended that you come in for maintenance every 4 to 6 weeks depending on your hair growth. Micro Locs fit in this category.
