Healthy, well-hydrated hair should have some stretch or elasticity. Without it hair becomes brittle and can break. With too much stretch your hair can become matted and gummy.
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.

If your hair is healthy and has a good protein/moisture balance, it should have some elasticity and be able to stretch a bit, about to 120% it's normal length while it's wet, and then bounce back to its size after you release it.
To begin, you must understand 2 main causes of stringy hair: oily hair and fine hair. This can happen due to the most common mistakes: incorrectly applying conditioner, combing hair right after showering, ignoring split ends, using unsuitable pillowcases, and sebum or product buildup.
Over-hydrated hair can become overly flexible and stretchy, while extremely dry hair can become brittle and less elastic.
At this point, healthy hair will bounce back to its previous state – whilst overly-stretchy strands will take longer to do so; the worst cases won't bounce back at all or could even snap off.
Medium elasticity: Most women's hair falls under this category. You'll know this is your hair type if your hair stretches partially before breaking.
Once the strand is wet, stretch the hair. If the hair bounces back to its original length without breaking, then your strands are balanced. However, if the strand doesn't bounce back, looks limp, or breaks, it's definitely in need of a protein boost.
Healthy hair can be stretched up to 30% of its original length without breaking when wet. This elasticity is increased due to water molecules that make the hair more flexible. However, care should be taken to avoid excessive stretching, as it can lead to damage.
When you add an excessive amount of protein to your hair you're creating an intense barrier on your strands. Protein buildup like this can be a real problem as water and other moisturizing ingredients aren't able to penetrate the strand, leading to dry and dull hair that may feel limp and stiff.
If you regularly wear a tight ponytail or braid over a long period of time, the recurring pressure and stress at the root of the hair can lead to an increased loss of healthy hair.
Hair has a strength to weight ratio comparable to steel. It can be stretched up to one and a half times its original length before breaking.
If you notice your tresses have become stringy, limp, or gummy (meaning hair stretches like a rubber band and snaps) you could be lacking protein.
A piece of material is clamped in a vice. A fixed weight is hung from the end and the material bends / deflects. When the weight is quickly removed, the material 'springs back'. The amount of deflection, is a measure of its elasticity.
Healthy Hair vs.
While healthy hair feels smooth, has minimal breakage, and appears shiny, unhealthy hair usually has frizz, split ends, roughness, and a lack of luster. All of these latter signs point to intrinsically weaker hair1.
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.
Healthy, well-hydrated hair should have some stretch or elasticity. Without it hair becomes brittle and can break. With too much stretch your hair can become matted and gummy.
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.
Using too heavy or greasy products can weigh down your hair and make it more likely to bend. Be sure to use light, airy products that won't weigh your hair down. Also, please avoid using any products that contain alcohol. These products can dry out your hair and make it more likely to curl.
Healthy hair should have some elasticity, meaning it should allow for some stretch before it breaks. When hair moisture and protein levels are depleted, it loses this ability which can make hair prone to breakage, a telltale sign of damage.
1.HAIR LOOKS AND FEELS DRY AND BRITTLE
It's lacking in shine, it's permanently parched, and it's more difficult to style as a result. Hair strands can dry out for a whole raft of reasons, whether it's because of heat damage Opens in a new tab, bleach damage Opens in a new tab, or just simple genetics.
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.
