Using products that are designed to nourish the scalp and hair can definitely speed up this process, but on average you'd be looking at six months to a year to fully see a difference in your hair's condition.
Sadly, there's really no way to heal damaged hair. Hair is not a living tissue with regenerative abilities, so it can't heal. It has no nervous system, blood, or living cells.
using heat-based drying and styling tools too frequently. shampooing too often. using a shampoo with harsh ingredients, such as sulfates, that are drying for your type of hair. not using a conditioner often enough or one that's designed for your type of hair.
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.
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.
Because hair is not a living tissue with regenerative ability, it cannot heal and repair. You can use oils, conditioners, hydrolyzed proteins or other ingredients to disguise the issues temporarily but it's akin to using makeup on the face.
Use A Hydrating Shampoo.
These shampoos tend to be creamy, rather than clear in texture and are formulated with moisturizing ingredients like jojoba, argan, avocado, almond or apricot kernel oil. Other ingredients like glycerin and aloe vera also help hydrate parched ends.

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.
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.
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 your hair feels like straw, it's more than likely because it lacks moisture. A great place to start when it comes to solving dry locks is your haircare regime. Switch things up with different products and be sure to introduce a nourishing treatment mask.
A variety of factors may cause brittle hair and nails. One of them is a lack of biotin. Biotin, also known as vitamin B7, helps the body convert food into energy. A deficiency in biotin is very rare, but when it occurs, brittle, thinning, or splitting hair and nails are some of the most noticeable symptoms.
While Vaseline doesn't have any moisturizing properties, the protective layer it creates can lock in moisture from moisturizing products. This might make your hair less prone to breakage. There's no scientific evidence to support the popular claim that Vaseline makes your hair grow faster.
Biotin. Biotin is an essential B vitamin (meaning we need to consume it daily) that's known to be important in hair and nail growth. "When patients have a biotin deficiency, they suffer from thinning, dry hair, and dry skin," says Zeichner.
