Just like your skin, hair can dry out when exposed to the cold or changes in temperature (like when you step inside from the cold). Cold and heat can make your hair lose moisture, and water makes up 10% of hair. Your hair will feel rough and may make a crackling sound when you touch it.
Hair loss, dull hair
Have you recently gone through some tough times? Logging lots of overtime at the office? Your hair, which grows about 1.2 cm per month, can feel the effects, even weeks later.
Dull, dry, brittle hair
Dyes, perms, relaxers and other chemical treatments act in the same way a stripping agent works on furniture. The more you use them, the more your hair feels the strain.
You aren’t rinsing your hair properly. You don’t need to use half a bottle of shampoo to wash your hair. Too much shampoo makes rinsing more difficult and could result in residue on your hair, which weighs it down and makes it dull.
