Doesn't your hair get really frizzy and a total mess during the rainy season? That's why I always apply hair oil, haha. It's a perfumed hair oil, and it's so good with a lovely scent. Plus, the amount of oil is really generous, so it offers excellent value for money. If you put a small amount in your hands and apply it to your hair by combing it through, it spreads really well, haha.
I tend to apply it right before drying my hair when it's still slightly damp. When do you all apply it? Haha.
