Careless brushing does more harm than gain. But there is no harm in softly brushing the back of the hair to full length by bending, or taking the hair on your front by parting them in two halves from the middle. Brushing the glands of lard activates to produce natural oils, which makes the hair silky and shiny.
Start by brushing from the bottom up to the top until the bottom knots are not tackled. This will prevent your hair from breaking and the tangled hair will be more easily settled.
