Why Does My Hair Sometimes Look Blue?

The reason why your hair sometimes looks blue is because of a few different factors. If you are blonde, it is possible for your hair to appear bluish because of sunlight reflection. Also, some blonde shades can be more sun-sensitive and thus appear bluer than other shades from the same brand.

DHT occurs naturally but when you have too much, it causes your scalp to produce more oil. Oil attracts dirt and bacteria which lead to inflammation, redness, and discoloration – all signs of common scalp conditions like dandruff.

5 Tips to Keep Your Hair Healthy After Hair Dye

It is important to keep the hair healthy after using any hair dye color. The following tips will help

1. Always wash your hair with a good conditioner

Hair dye is harsh on your hair, and without a proper conditioner, there is a high chance that your hair will look like straw after dying it. To ensure that your colored hair maintains its healthiness and shine, it is important that you keep your hair moisturized by using the appropriate conditioner for your hair type.

A leave-in conditioner or mask is a great way to do this because it can always be applied right before or after using heat on your hair.

2. Sulfate-free shampoo

sulfate-free shampoo is another way to keep your hair healthy because it helps preserve natural oils in the hair and prevents dryness caused by chemical dyes. When washing your hair with a sulfate-free shampoo, use cool water instead of hot. This will help prevent heat damage and minimize frizz.

3. Protection against heat

The components in heat protection sprays, in particular, work to lessen heat damage, probably by balancing how the hair heats up. However, you will need to limit the amount of time your hair is exposed to heat styling as they can’t protect it from the majority of the harm.
