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 in your hair is a good sign, but just like with moisture, too much of a good thing can be fatal for your hair's health.
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.
Hair Elasticity
It refers to how long a single strand of hair can stretch before it returns to its normal state. In order to find out what the elasticity of your hair is, wet a strand of hair and stretch it as much as you can. This will determine whether your hair falls under high, medium or low elasticity.

Stretching natural hair is a way of temporarily loosening the curl pattern to control tangles and shrinkage. You may find that it helps you moisturize and style too because you can get your fingers through it quicker. When your hair isn't manageable, it can be time-consuming and lead to breakage.
Mechanical testing (tensile) of single hair fibers
From the tests, it is found that hair is very elastic and can be stretched up to 50% of the initial length. In few samples, hair curling was observed immediately after the fracture at one end of the sample.
If your hair lacks elasticity, try incorporating protein treatments, deep conditioning, and gentle handling techniques into your hair care routine to help restore elasticity and prevent future damage.
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.
Stretching Can Reduce Tangles
In the same vein, regular stretching of your natural hair can prevent all types of knots and tangles by keeping the strands elongated. When your curls are in their natural state, it can sometimes be very easy for the curls and coils to become locked together in breakage-causing knots.
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.
There are MANY REASONS hair can lack BOUNCE and BODY – be it STRESS, a LACK OF VITAMINS or, simply, AGE.
Anyone who wears tight hairstyles or puts repeated stress on their scalp can get traction alopecia. Some people experience traction alopecia more often than others because tight hairstyles are common in their culture or profession. This is especially true for girls and women of African descent.
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.
Wet hair with normal elasticity can stretch up to 50% of its original length without breaking. This means that if you have a strand of hair that is 10 cm long when dry, it can stretch to about 15 cm when wet.
Olive oil for hair is rich in fatty acids and antioxidants and can thus help promote faster hair growth. It can also provide many wonderful health advantages, like nourishing and strengthening your hair, and reducing bacterial infections.
Coconut oil can have many benefits for your hair and scalp. It is used to relieve dandruff, restore luster to dry and damaged hair, tame frizz, and protect hair against styling damage. It is safe to use on all hair types.
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.
If lifestyle changes and anti-aging skincare products have not produced the results you're after, medical treatments may be the next step. Medical procedures performed by a cosmetic dermatologist can improve skin elasticity by stimulating new collagen growth.
Start by taking a strand of clean, damp hair and gently stretching it between your fingers. 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.
How strong is our hair? A single strand of human hair has the potential to support around 100 grams of weight.
Your hair strands hold moisture in the cortex, a.k.a., the center of the hair strand. The cortex is surrounded by the outer layer, known as the hair cuticle. If your hair texture becomes too dry, the hair cuticle can lift & cause the cortex to lose its moisture. This results in a loss in elasticity.
