Why is my hair flat? How to bring volume back to limp and fine hair

Does your hair often look limp, lack bounce, or refuse to hold shape no matter what you try? Are you always asking yourself, “Why is my hair flat?”.

Flatness can feel like a daily frustration if you have fine or thinning hair. Even people with naturally thick hair can experience a drop in volume.

If you’ve been dealing with flat hair woes, there’s good news! Flat hair isn’t something you simply have to put up with.

Once you understand what’s going on with your strands and scalp, you can start building a haircare and styling routine that lifts, defines and enhances your natural texture, without weighing it down.

We’ll explore why hair goes flat, what causes limpness near the roots, and how to add volume to fine hair in a way that’s healthy, sustainable and true to your hair’s needs.

What causes flat hair?

Hair often falls flat due to a few overlapping factors:

Hair type – Fine or thin strands naturally sit closer to the scalp.
Scalp condition – Oil, buildup or imbalance at the roots can reduce lift.
Product use – Heavy formulas or residue can weigh hair down.

The scalp plays a key role. When oil builds up or cleansing is inconsistent, residue collects near the roots and flattens the hair. Even with dry or sensitised ends, oily roots can drag everything down.

Styling habits make a difference, too. Air-drying without shaping, brushing too early, or skipping heat protection can all contribute to collapsed roots and reduced volume.

Once the root cause becomes clear, scalp, styling, or product, the path to restoring shape and fullness gets a lot simpler.

Signs of Limp and Fine Hair

Fine hair is a specific hair type, whereas limp and flat hair can happen to people with various hair types.

That said, fine hair is often more prone to falling flat in comparison to others. Here are some of the things to look out for:

Hair that falls flat against your scalp: This means your strands sit very close to your scalp and head.
Limp hair: Hair hangs down and looks lifeless or lacks body and doesn’t have volume in its lengths or near the roots.
No movement or undefined shape:If you find your curls or coils have no definition or bounce or if straighter strands have very little movement or shape, it could point to flat hair.

How to Fix Flat Hair: Flat Hair Solutions & Root Lift Techniques

Flat hair and fine hair aren’t the same.

Fine hair refers to the thickness of individual strands; they’re smaller in diameter, more delicate, and often more fragile. Flat hair describes how the hair sits: close to the scalp, with little lift, movement or body.

It’s possible to have thick hair that falls flat, especially if the strands are heavy or weighed down by product. Likewise, fine hair can look full and voluminous with the right cut and styling routine.

Understanding this difference matters when choosing how to care for your hair. Volume loss often comes down to product build-up, oil near the roots, or styling habits, not necessarily hair density or strand thickness.

Step 1: Start With a Clean, Balanced Scalp

Product build-up is a major reason why hair lacks volume. When styling creams, oils, or even your shampoo don’t rinse out properly, they coat the hair shaft and clog follicles at the root. That’s why a weekly scalp detox is essential.

Incorporating a clarifying or detox shampoo into your routine, like the Davines SOLU or Naturaltech Detoxifying Shampoo, helps deeply cleanse the scalp, remove impurities and create a fresh foundation for volume.

Follow with a lightweight conditioner that hydrates without leaving residue.

Keep in mind that over-washing can also lead to problems, especially if it prompts your scalp to produce more oil to compensate. A balanced routine that includes regular but gentle cleansing is your best bet.

Step 2: Choose the Best Volumising Shampoo for Your Hair Type

The right shampoo can make a noticeable difference in how your hair behaves. Volumising shampoos work by lifting at the root, reinforcing the hair’s structure and preventing strands from clumping together.

Davines VOLU Shampoo is formulated specifically for fine or limp hair, offering a lightweight cleanse that builds volume without drying out your scalp. Pair it with our DEDE Conditioner, a gentle, weightless moisturiser designed to soften the hair without flattening it.

Looking for even more body? Naturaltech Energizing range supports scalp health while thickening the appearance of each strand by up to 10%. Try the Energizing Shampoo and Thickening Tonic together for a volumising effect that also nurtures your scalp.

Step 3: Dry Your Hair for Maximum Lift

How you dry your hair after washing can make or break your volume.

If you usually towel-dry and leave it to air dry naturally, this may contribute to your flatness. Instead, try flipping your head upside down and using a blow dryer with a diffuser to direct airflow towards the roots.

Focus on lifting the roots as you dry, use your fingers or a round brush to create gentle tension and push the hair upwards, encouraging shape and movement.

Apply a root-lifting mousse or serum while your hair is still damp for even more hold. Davines’ This Is A Volume Boosting Mousse is ideal here; it’s airy, weightless, and gives noticeable lift without stickiness.

Pro tip: If you’re short on time or prefer air drying, try clipping sections of your hair up at the roots while it dries. This will help set the root direction upwards instead of letting it settle flat against your scalp.

Step 4: Style With Intention

When it comes to styling fine or limp hair, less is often more, especially near the roots. Heavy creams, oils or serums will weigh hair down fast, so stick with light sprays, mousses or dry textures that encourage movement.

This Is A Dry Texturizer or Dry Wax from Davines are brilliant options for adding shape and definition without greasy residue. Just a few sprays around the crown and mid-lengths are enough to make your hair feel more alive and voluminous.

Need more hold for a night out? Try the OI Liquid Luster or OI Soufflé. These stylers bring together shine, volume and body in one gentle formula, great for creating a polished look that still feels natural.

Detoxing Your Hair for More Volume

Don’t let build-up bring your hair down. A quick-and-easy detox routine will deeply cleanse your scalp and remove any product, oil, or grime that could cause your hair to fall flat.

Our scrubs and detoxifying shampoos are great tools to have on hand exactly for this reason. Not only this, but they’re important for combatting other hair concerns too, like dullness and excessive oiliness.

Hairstyles for Fine, Flat Hair That Add Instant Volume

Your haircut has a huge impact on how full your hair appears. If your hair is very long and fine, the weight may drag it down. A shorter style, or one with soft layers, can immediately create more lift and texture.

A long bob or layered mid-length cut works particularly well for those with fine hair, as it adds shape without sacrificing length. Adding a fringe or curtain bangs can also give the illusion of fuller hair, particularly around the face.

You can also play around with your parting. A deep side part or a slightly messy middle part can make the roots appear more lifted and reduce the appearance of flatness.

For those looking for even more volume, hair extensions or temporary pieces like clip-ins can offer a confidence boost for special occasions without committing to long-term changes.

Drying Techniques for More Volume

Wondering how to style fine hair? Thinking about how you dry it is a great place to start, especially as a long-term strategy. Try using a volumising mousse and flipping your hair upside down for a few minutes as you dry it.

Using a blow dryer and a barrel brush is another great tactic for increasing volume.

Thanks to the heat and air flow, this often works much better than leaving your hair to air dry. Be sure to focus on your roots, pushing them up and out rather than smoothing them down if it’s a voluminous look you’re after.

If you prefer air drying, it’s still possible to get more volume. Start by gently towel-drying your strands, then apply a volumising mousse or serum and scrunch. You can also use clips to hold your hair in place whilst it dries, lifting it up. Once it’s dry, use a spray like our Dry Wax around the roots for extra body and definition.
