Balance oily hair!
Overwashing and environmental factors are the most common causes of oily hair. It can also result from the wrong hair care products, excess heat, and humidity.
If you have oily hair, it can be tempting to wash it every day, but don’t do it; it can make the situation even worse! Choose a shampoo that has tea tree oil: which regulates oil production and therefore helps balance oily hair.
Applying conditioner properly may make or break oily hair. Use it only on the ends and avoid the scalp; this will protect your hair from looking oily and flat.
Tip: Dilute apple cider vinegar in a cup of water and pour it through the hair. Leave for a few minutes, and just like magic, the buildup is gone and the hair is squeaky clean and 100% grease-free.
