Signs of dry hair

Before getting into how to prevent dry hair, let’s learn to spot it. There are a number of things to look for that can signal dry hair. Signs of dry or dehydrated hair include: frizz, flyaways, brittleness and breakage.

Dehydrated hair symptoms

Generally speaking, dehydrated or dry hair will look dull and be more difficult to manage. This is because dry hair means raised hair cuticles and therefore hair fibers that are more porous. This can lead to a weakened structure and diminished health. In some ways, dehydrated or dry hair can signal that your hair needs a little TLC.

How to spot dry hair early

You can identify dry hair early by looking for the warning signs: dullness and frizz can be giveaways that you have dry hair. Brittleness and split ends can be signs of dryness, too. A tight or itchy scalp can also indicate dryness.

Causes of dry hair

Now that you know how to call it when you see it…what are the causes of dry hair? Air quality and temperature can be a factor – the colder seasons can be harsh on your mane. That said, hair washing can also be a major factor or cause of dry hair. Overwashing can strip the hair of its natural oils, drying it out. Similarly, excessive heat styling can cause all kinds of damage and dryness. Overbrushing, too, especially wet hair, can pull and damage hair making it more susceptible to dryness. Chemical treatments (like hair dye or bleach) can also be culprits when it comes to hair dryness.

Best practices for dry hair prevention

To prevent hair dryness, consider your haircare and styling routine – from washing to brushing, from drying to styling – and make sure you’re being gentle and caring. It’s all about developing healthy hair habits. Some basic prevention tips for dry hair include being careful not to overwash your hair or to use excessive heat when styling. Being mindful of scalp care is important, too. We’ll get into some specific hydration and deep conditioning tips below.

Hydration routine

For a proper hydration routine, use products that can really hydrate the hair, like Absolut Repair range by L’Oréal Professionnel. These products, including a shampoo, conditioner, mask, and oil, are lightweight, yet deeply hydrating and nourishing, and work to restructure damaged hair.
