Noticed your hair looking thinner? If so, you might want to familiarize yourself with the most common ways to achieve thicker-looking hair.

Let’s start by clarifying that everyone loses hair, up to 150 strands per day, and shouldn’t make any noticeable difference in your hair’s appearance. However, there are several factors that may be causing your hair to appear thinner than usual, including bad hair habits and to the type of haircut you have.

In this article, we’ll closely look at what is fine hair and provide you with advice on how to make thin hair look thicker so you can apply the most suitable fine hair treatment.

What is fine hair?

Simply put, fine hair is hair that lacks volume and thickness and can occur in specific areas like around the temple, or all over the hair.

Having fine hair has nothing to do with the rate at which your hair falls out, but is about the dimensions of your hair strands, which are simply smaller in circumference.

You might feel that having thin hair prevents you from achieving your desired style, but there are plenty of things you can do in your hair care and styling routine that can help give you a boost of volume and confidence. Read on for our top tips on how to make thin hair look thicker.

What causes thinning hair?

Many of us will experience our hair thinning at some point in our lives, especially as we get older. But if you feel that your thinning hair is more significant than age-related, here are some areas you should be aware of.


Your genetic make-up is also a factor in thinning hair. While you can’t change this, you can control how you look after your hair. Keeping it looking healthy and well maintained with a salon quality collection of products like TRESemmé Full Fiber Volume Shampoo and conditioner system is paramount.

This salon quality shampoo is formulated with a Collagen and Peptide Complex™, to deliver instant lift and body to fine hair. Always follow up with a volumizing conditioner. If you’re worried that a conditioner might weigh your hair down, we recommend the TRESemmé Full Fiber Volume Conditioner for Thin Hair, which delivers lightweight hydration and enhanced grip that can be re-touched throughout the day while leaving your hair feeling weightless and easy to style – so you can achieve your desired look.

Apply a generous amount of the shampoo to your hair, massaging it into the roots to form a lather. Rinse thoroughly with warm water and follow up with the conditioner. Only apply the conditioner to your mid-lengths and ends, using a wide-tooth comb or your fingers to detangle as you go. Rinse thoroughly. Blow dry your hair afterwards, using a diffuser for maximum volume.

Break hairstyling habits

Using poor quality products, applying heat too frequently and not protecting your hair at night are just some of the ways in which we weaken our hair. When it comes to learning how to help make fine, thin hair look thicker, you should refrain from these habits and replace with a healthy hair routine.

Using salon quality hair products is also a step in the right direction. If you want to know how to make thin hair look thicker, we suggest using the TRESemmé Volume Thickening Spray, a unique spray that will hold your volumized style in place all day.

To apply, lift sections of your hair and direct the spray on to your roots. This will give it a more volumized base. You can also spray it through the mid-lengths to ends of your hair if you want to add some extra texture to your style.

Focus on styles that enhance volume

The easiest way to make thin hair look thicker when styling is with a swept over side-parting. After following the root-lifting technique mentioned above, take a comb and create a parting at the side of the scalp and sweep this section of your hair over to one side. Finish with hairspray to lock in the style.

Another easy way to add volume is with a bouncy blow dry. After washing, pat hair dry with a towel and blow dry with a diffuser attachment. Tilt your head upside down and blow dry your hair this way until it’s nearly dry. Next, take some large curlers and section your hair coming forward until you have reached the crown, then downwards to the nape of your neck. Eight to ten curlers should be enough, and spray with some finishing spray [insert product recommendation here]. Wait ten minutes and then remove the curlers, running your fingers through your hair. Add some hairspray  TRESemme 24 Hour Body and Volume Mousse to finish.

When it comes to the best cuts for fine hair, shorter styles can give the illusion of more volume. A chin-length angled bob looks timeless and classic, while giving thin hair more body and shape.

If you prefer to wear your hair longer, try a wavy, tousled style with some light layers cut in, together with feathering at the ends. Layers can add instant volume, especially when enhanced by applying TRESemmé Volume Thickening Spray at the roots.

Remember, knowing the root causes and how to make fine, thin hair look thicker will allow you to make the necessary changes. In doing so, you will help your hair flourish and feel confident with your style.
