One reader wanted to know if it was okay to apply Megatek to your entire head or just scalp only..
Well Paola...that depends.
If you are using as a protein treatment/conditioner that you plan to rinse out, then apply to your entire head. Protein makes your hair strands stronger and more durable. If you have a relaxer, protein is very important.
Applying to scalp will give you growth, although many people have reported growth BOTH ways so you can't go wrong.
If the Megatek gives you headaches, I recommend diluting with oil (vatika, extra virgin olive oil, etc.)
