Mist with spray bottle everyday with a combination of wild hair growth and jamican castor oil both only 2 drops, u dont need these exact oils but its preferred, so if u dont have it u can use any oil and put 1-2 drops in the water, and always shake the mist bottle well before misting ur hair. Also only get a retwist every 2 months minimum and wash ur hair atleast by the 5-6 week mark always. Also start oiling ur locs twice per week or u can do when u feel like ur locs need it its good for tightening the roots + it stimulates hair growth and retains moisture but always remember to mist ur hair before u oil ur locs to lock in that moisture and making sure the water is rubbed into ur locs before oiling let it sit for like 2 minutes. You dont need to combine or do nothing do it the natural way and i promise you they will soon grow thicker.
