How to blow dry and add volume to your hair
Wash your hair with shampoo and then apply conditioner.
Choose shampoo and conditioner that are right for your hair type. If your hair is dry, buy a moisturizing shampoo.
Available options:
(a). If your hair is too oily, buy a shampoo designed for oily hair. Use a volumizing conditioner, unless your hair already has too much volume.
(b). If your hair is curly, use a straightening spray. Make sure you use the right products.
(c). If your hair is fine, buy a shampoo with ceramic or silicone moisturizing properties. For medium to thick hair types, you can use sulfate or normal conditioner.
(d). If your hair is fine and dirty, shampooing may get it wrong. Talk to your hairdresser before you wash your hair if your scalp cannot handle it.
