I put that it looks good all year round not because I'm vain but because I know what to do and not to do all year round to make it look good.
But in terms of how healthy it actually IS and the least effort needed, definitely summer. I love the softness of my hair in summer and the humidity keeps it moisturized. In winter it is dry and so it is harder to avoid brittle hard hair and more work to get it to be soft.
Get used to me. Black, confident, cocky; my name, not yours; my religion, not yours; my goals, my own; get used to me. -Muhammad Ali
