Oils have been shown to help rehydrate the hair and smooth the cuticle. Olive oil, in particular, is said to help soften the hair and replenish much needed moisture. It's also easy to work with and relatively inexpensive. Just be sure to wait a few days post-coloring before you do an olive oil treatment.
Typically dry hair appears flat and dull, think no shine. Dry hair is also usually more difficult to manage and when you touch it, it has a noticeably brittle texture i.e. knots and tangles, etc. If your hair isn't maintaining a blow-dry this can also be a sign that your hair is lacking hydration levels.
Tangling, knotting, frizz, dullness, breakage: these are all signs of very dehydrated hair. The good news? There are easy ways to treat and prevent not just the annoying symptoms of dryness, but the dry, dehydrated hair itself.

Take one strand of wet hair from your head, pinch each end with your fingers, and gently pull at it. If the hair stretches and then returns to its original length, it's healthy! (Nice). If it stretches but doesn't return it's dry.
Frizziness is caused by dry hair that lacks moisture. Ironically, humid, wet weather tends to make frizzy hair worse. That's because dry hair tries to absorb moisture out of the air, causing each hair's cuticle, or outer layer, to swell up, instead of lying flat.

Having low hair porosity or even high hair porosity and using the wrong products can also contribute to having dry hair, even when using a conditioner. Low porosity hair is hard to hydrate while high porosity hair loses moisture easily.

Dry, brittle hair shouldn't be taken lightly— it's something that must be treated. Brittle hair could be the result of a number of things, right from constant heat styling, to medical conditions, such as malnutrition, hypothyroidism and a biotin deficiency.
If you have low porosity hair, it means the structure of your hair doesn't easily allow moisture to be absorbed into your hair shaft. This can make it harder for water to saturate your hair when it's washed. Because this type of hair tends to repel moisture, it can also be more challenging to process and style.
