Hair Elasticity: What It Is, How to Test It, and How to Fix It

What Is Hair Elasticity?

Why Hair Elasticity Matters

Hair elasticity can be defined as the ability of hair to stretch and return to its original shape without breaking. Think of a healthy strand as akin to a good-quality elastic band; it gives a little under tension, before springing back.

The secret of elasticity for hair lies in the shaft, particularly the cortex. Contained within this middle layer are keratin proteins held together by different bonds, including hydrogen bonds that allow temporary stretching.

When you pull your wet hair gently, these bonds shift, with the strand lengthening as a result. In fact, healthy hair can stretch up to around 30% of its length when wet and bounce back. Hair doesn’t stretch so far when dry, typically up to about 20%.

Here at Cliphair, with over 17 years of hair expertise since 2007, we’ve helped thousands of people restore healthy hair. That has included many women who have been worried about their hair elasticity.

In this guide, then, we’ve set out the vital things to know about stretchy hair, including the steps of testing and fixing it.

Signs of Good vs Poor Hair Elasticity

So, if you’ve ever wondered, “how elastic should hair be?”, you already have at least one answer: around 20% to 30%, depending on its dryness or wetness.

But given that a number on its own might not seem very meaningful, it can also be helpful to know what healthy or unhealthy hair elasticity actually looks like.

Signs of good hair elasticity, for example, include your hair:

• Stretching gently when wet, then springing back quickly.
• Feeling smooth and resilient.
• Holding curves or waves well.
• Showing natural volume and movement (it “bounces”).

As for the common indicators that you don’t have such healthily stretchy hair (poor elasticity), those include your hair:

• Stretching excessively like an old rubber band and then staying stretched or snapping.
• Feeling gummy or mushy when wet (often called “gummy hair”).
• Breaking easily, particularly when wet.
• Failing to hold a curl and generally looking flat or limp.

Gummy hair is usually a telltale sign of protein loss, while hair that snaps instantly is often overly dry. A hair elasticity test can help draw attention to the exact issue.

What Causes Poor Hair Elasticity?

Heat and Chemical Damage

One of the most common culprits for poor hair elasticity is excessive heat styling. Straighteners, curling wands, and blow dryers expose the hair shaft to high temperatures that gradually break down keratin proteins and weaken the bonds that are so crucial for keeping hair strong.

Chemical processing can bring about even more damage to hair elasticity. Colouring, particularly bleaching, strips proteins from the cortex. Meanwhile, the hair’s internal structure is weakened over time by perming, relaxing, and repeated highlights.

Among the customers that we hear from, bleaching is the most frequent cause of lost hair elasticity.

If you’ve recently lightened your hair and it now seems to stretch too much, you’re far from the only person to experience this. Many people search online for answers on how to fix elastic hair after bleaching; the key is targeted protein care and gentler routines.

The Protein-Moisture Imbalance

Another potential answer to the question “why is my hair stretchy?”, is the protein-moisture balance in your hair not being quite right.

It’s certainly an easily overlooked and often misunderstood factor in poor hair elasticity. Your hair needs protein for structure, as well as moisture for flexibility.

In summary:

• Too much moisture without enough protein

  This combination can leave you with overly elastic, gummy, and stretchy hair. The strands swell excessively when wet but aren’t strong enough to bounce back.

  An under-recognised cause of this problem is over-conditioning or “moisture overload” from heavy masks and leave-ins without protein. Damaged or porous hair can be particularly susceptible in such cases.

• Too much protein without enough moisture

  If this is the situation with the protein-moisture balance in your hair, it will likely feel brittle. Your hair will feel hard, snap easily, and lack stretch.

The clue to dealing with either of these extremes lies in the word, “balance”.

The hair elasticity test will reveal what you probably need to do. Excessive stretch can usually be remedied with more protein. If, on the other hand, your hair barely stretches or instantly snaps, greater moisture will typically be necessary.

Environmental and Lifestyle Factors

There are a number of factors to bear in mind when it comes to hair elasticity problems, such as:

• Hard water minerals that build up and dry hair. This is a particular issue in certain parts of the UK such as the South, East, and Midlands.
• Sun exposure and chlorine from swimming.
• Poor diets low in protein or biotin.
• Over-washing or the use of harsh sulphate shampoos.
• Instances of rough handling such as aggressive towel drying, tight ponytails, or sleeping on pillowcases with surfaces that cause friction.

These elements can all gradually erode hair elasticity. For further information on repairing general damage, check out our guide on how to fix damaged hair.

How to Test Your Hair Elasticity

The Wet Stretch Test (Step by Step)

Unsure how to check hair elasticity? In that case, give the “wet stretch” test a go. This hair elasticity test is simple, reliable, and trusted by professionals.

Here’s how to do it:

• Step 1: wash or dampen a section of hair

  This test works best with hair that is clean and wet. You can perform it after washing or lightly dampen a small section.

• Step 2: isolate a single strand from mid-head

  Choose a strand from the middle section of your hair, instead of from the hairline or crown.

• Step 3: hold at the root and gently stretch from mid-length

  Hold the strand securely near the root. Using your other hand, gently stretch the strand from the middle, taking care not to pull aggressively.

• Step 4: Release and observe

  Watch how the strand behaves when you let go. The way it reacts will tell you a lot about its current condition.

There you have it! This simple elasticity test for hair allows you to quickly and easily test the stretchiness of your hair in the comfort of your own home.

Reading Your Results

• Good elasticity: the strand stretches slightly, around 20% to 30%, and returns immediately to its original length. This indicates a solid protein-moisture balance.
• Medium elasticity: your hair stretches more than ideal and takes a second or two to return. You can treat this as an early warning sign of the need to adjust your routine.
• Poor elasticity: the strand stretches a lot, stays lengthened, feels gummy, or breaks. This suggests a significant loss of protein or an imbalance that requires urgent attention.

This hair elasticity test gives you a clear picture of your protein-moisture balance. Overly stretchy results point to a need for protein treatments, while minimal stretch indicates you should be looking to boost moisture.

How Hairdressers Use the Elasticity Test

This is a widely used elasticity test in hairdressing. Professionals perform this hairdressing elasticity test before providing chemical services like colouring or perming. It will help them determine whether your hair can safely withstand processing.

If elasticity looks poor, a professional may recommend protein treatments first. Alternatively, they might adjust the formula to be gentler.

How to Improve Hair Elasticity

Rebalance Protein and Moisture

In almost any conversation about how to improve hair elasticity, protein-moisture balance will have a prominent part.

The key is to match your treatments to your test results:

• If your hair feels too stretchy or gummy, turn to protein-rich treatments with ingredients like keratin, hydrolysed wheat protein, or silk amino acids. These rebuild structure inside the shaft.
• If your hair feels brittle and snaps easily, make deep moisture your focus. The likes of hyaluronic acid, glycerin, shea butter, or argan oil can greatly help here.

Alternate weekly, with one week involving a protein treatment, and the next week concentrating on moisture. Avoid overloading on either. Browse our hair care products for options that suit extensions and natural hair.

Of course, knowing how to fix hair elasticity is one thing; being aware of the typical timelines for visible improvement is another. If you’re curious about the latter, check out our article on how long it takes to repair damaged hair.

Reduce Heat Damage

Another element of how to get elasticity back in hair, is minimising heat damage. So, make sure you lower the temperatures of your heat tools. This should be a maximum of 185°C for most hair types.

Remember, too, to always use a heat protectant spray before styling. Our own heat protectant spray here at Cliphair offers effective defence.

Limit heat styling to two or three times a week. It can be well worth considering heatless methods as well, for pulling off those curves or waves.

Adjust Your Washing Routine

• Switch to sulphate-free shampoos to avoid stripping natural oils.
• Don’t over-wash; two or three times per week is sufficient.
• Use lukewarm water rather than hot, as high temperatures will swell the cuticle.
• Apply conditioner from your mid-lengths to the ends only.

These might all seem relatively small changes. But when you combine them with the use of the right haircare products, they can go a long way to preserving your hair’s moisture and protein balance.

Use Hair Extensions as a Protective Style

While your natural hair recovers, quality clip-in extensions can boost length and volume without your hair needing to be exposed to extra heat or chemicals.

Clip-in hair extensions are a temporary, DIY-friendly solution that you can apply and remove yourself. Our clip-ins here at Cliphair use 100% Remy human hair that blends naturally, and you can count on them moving just like your own hair.

In the longer term, permanent extensions like tape-ins, wefts, or nano rings can seamlessly integrate with your natural hair. However, such permanent hair pieces should always be fitted and maintained by a qualified hair extension specialist.

When to See a Professional

If a hair elasticity test shows severe damage such as your hair snapping or stretching dramatically, you should consider booking a consultation with a trusted hairdresser. They will be able to assess the overall condition of your hair and recommend in-salon treatments.

For permanent hair extensions, professional fitting ensures safety and the best possible results. Never try to apply or remove bonded systems yourself.
