Its been nearly 5 years but i have decided to grow my hair out. Im a biracial male (half black/half white) that has naturally wavy/curly hair. But since my last attempt to grow it out have trained it to be straight and have not let it get longer than 2.5 inches. Currently its under an inch but I am willing to let it grow until it gets to curly as it used to be. What are some products and techniques to get there? Thanks in advance!
