It works. I put it on my head at night before bedtime (just rubbed some in my scalp) then in the morning I would wash my hair and fix as normal. Within a month, I had a lot of new growth.
This was pre CG. I still do it if I start getting those painful little bumps (very rare since going CG). I think it worked because those bumps may be caused by a fungus. HTH
Hair: 2a or 3a (not sure), very porous and fine as frog hair
Day 1: Cowash and condition with AO GPB, ACV Rinse,
Co-Kra gel (this stuff is fantastic)

Day 2: KCKT, KCCC, plop, KCCC, plop again, air dry
Day 3: Curly Kinks Satin Roots, Coil Jam
Day 4: IAGirl's PT, KBB DT, FSG

Co-Kra gel is my own concoction of okra boiled in coconut milk. It is a cross between FSG and KCCC and leaves my hair very soft and shiny
