I couldn't hold out for four weeks.
After I used my homemade glycerine-based spray on conditioner, and had to wash the stickiness out of my hair, I had too much slippage around the edges to hold out for four weeks.
Hard-headed is what my grandmother would have called me. Why did I have to learn the hard way NOT TO PUT ANY SUBSTANCES ON MY BABY SISTERLOCKS! I hope other newbies can learn from my mistake.
I'm posting some close-ups today.
