To get the perfect sisterlocks, it is required to do the initial preparation of the hair. This is the only hairstyle that requires a proper prep session before starting the loc journey. It is performed by washing the hair twice or thrice as your loctician guides you. For the first time wash, you need to wash the hair by doing a deep conditioning treatment to remove any dirt particles, sweating and moisturizing residues, and more. A deep cleaning session of hair wash using high-quality products is a good idea to get clean, fresh, and healthy hair. For the second or last wash, you need to do a hot oil treatment for your hair before final washing. This step is performed to lock the moisture in the hair to get shinny dreads at the end. Again, you can consult your loctician to get an idea of the prep sessions according to your hair type.
