2-Almond hair oil is the best to use. Use Elvive shampoo and conditioner by L’Oreal according to your hair type. Comb only after drying.
3-Protect hair with sun block and if one has dry hair, then apply leave-in conditioner to the ends.
4-Keep in mind your face cut, thickness of hair, height and build, and of course, your style quotient while going for a haircut/hairstyle change.
5-Colouring/ straightening/ perming hair permanently is completely possible with the right products and hair care.
6-Accessorise your hair with hair bands, jewels, combs, braids or beads.
7-My secret: I always plait my hair before sleeping. That's the best way to avoid breaking the hair.
