The Curly Girl (CG) Method was popularised by Lorraine Massey and quickly became a favourite of curlies worldwide. This is because it recognises that curly hair differs from straight hair and should, therefore, be treated accordingly.
Oil travels freely down the shaft of straight hair, and, without regular washing, oil buildup can leave the hair looking limp and greasy. On the other hand, the twists and turns in curly hair make it difficult for sebum (natural oil produced by the scalp) to travel down the hair shaft, making it difficult to retain moisture and leaving it feeling and looking dry and frizzy.
The CG method, therefore, is a regime designed specifically to enhance curl definition by moisturising curls and encouraging them to clump.
