Elasticity is a measure of how much your hair can stretch before breaking. When you pull on a strand of healthy hair, it should be able to stretch about 30 percent before breaking. If your hair stretches beyond that point, it is considered to be lacking in elasticity.
Hair is naturally elastic, but only to a certain extent. It doesn't have to stretch and break to be damaged. Overprocessed hair will stretch much further without breaking than non-damaged hair.
Hair is supposed to stretch. Elasticity (stretching and returning) is normal. It increases with water in the hair shaft. Hair that will stretch but not return is often (over)processed. Stretching hair (especially wet) can lead to breakage, just because it can doesn't mean you should.
Healthy hair readily absorbs and retains moisture. Hair that is adequately hydrated will also have a nice amount of spring or recoil once stretched. You hair should not appear rough or brittle and the ends of your hair should also be intact (not split or broken).
Hair is a remarkable fibre. A healthy hair can stretch up to 30% of its length, can absorb its weight in water and swell up to 20% of its diameter.
If it stretches slightly and returns to its original length, your hair has good elasticity. If it stretches significantly and breaks, your hair is likely damaged and lacks elasticity. If it stretches a lot without breaking, it may be over-moisturized or lacking protein.
Your hair retains moisture in its cortex, aka the inner layer underneath the cuticles. This allows your strands to maintain that natural bounce and movement necessary to allow your hair to stay flexible without snapping off at the first blowout.
A damaged hair strand refers to a hair fiber that has lost its natural structure and strength due to various factors such as heat styling, chemical treatments, and environmental stressors. Damaged hair strands may appear dry, brittle, and dull, and can also have split ends and frizz.
There are MANY REASONS hair can lack BOUNCE and BODY – be it STRESS, a LACK OF VITAMINS or, simply, AGE.
Healthy hair should have a degree of flexibility, stretching and then returning to its original length without breaking. This flexibility indicates that the hair has good elasticity, which is essential for resilience and bounce.
If you've recently highlighted or chemically treated your hair, you also need to use protein regularly. Protein treatments can help strengthen the hair shaft and restore its structural integrity. On the other hand, if your hair feels dry, frizzy, and lacks elasticity, it's likely in need of moisture.
It's easy to tell how dense your hair is with a simple mirror test. Grab a large handful of hair and pull it to the side. You have thin hair density if you can easily see your scalp, medium density if you can partially see your scalp under your hair, and thick density if you can hardly see it.
If the hair doesn't snap or break easily when you pull it tight and if it regains its shape, it has some healthy elasticity and strength. According to Dr. Joe “Healthy hair is like a rubber band because it has springy coils of keratin in the cortex. You can stretch it, and it will recoil.
1) Virgin hair
It lasts longer than other types of human hair because it is 100% pure and hasn't undergone any chemical processing. It is sourced from one single donor. Another differentiating characteristic of virgin hair is that the cuticles are intact and all of them are running in the same direction.
It refers to strands that have never been color-treated or chemically processed in any way. To get more specific, it's hair that is completely and totally free from perms, bleaches, color treatments, and dyes—and yes, highlights and ombré hair also count.
Excessive hair touching is a repetitive and addictive habit that can be extremely hard to stop and can lead to Trichotillomania - a hair pulling disorder. Many women who's hands are always buried in their hair, typically suffer from very dry ends, oily roots, hair loss and poor overall hair condition.
Generally, he says, the range is somewhere between once a day and once a week. “If you have very fine or thin hair, you may need to wash more often, while those with thick or curly hair may need to wash less often,” says Dr Elizabeth Bahar Houshmand, a double board certified dermatologist and hair health expert.
If the balance becomes disrupted due to natural moisture loss or damage then the resulting loss of elasticity can leave hair difficult to style, dry and prone to breakage. Healthy, well-hydrated hair should have some stretch or elasticity. Without it hair becomes brittle and can break.
An easy way to add protein to hair is with a weekly deep conditioner treatment that saturates strands with nourishing protein-centric ingredients.
Proper hydration, nourishing, and hair care practices can fix hair damage and restore its elasticity. Hydrate and nourish hair for elasticity. Include zinc, biotin, and vitamins in diet. Stay hydrated to prevent breakage and promote hair health.
