How to make thin hair look thicker


Whether your hair is tightly curled or poker-straight, if it’s thin, it can look a little lifeless from time to time. While a good haircut can do wonders, rest assured: there are steps you can take at home to add volume and keep that salon-styled look for longer. Check out our seven insider tips below for how to make thin hair look thicker. 

1. Switch up your routine

If your conditioner adds more weight to your locks than you'd like, our revolutionary new TRESemmé Beauty-Full Volume collection could be just the ticket. Specially formulated with a unique reverse-wash system, use the pre-wash conditioner first to soften your strands, then follow with the shampoo to wash away the weight. The result? Natural, everyday volume which is soft and smooth to touch.

2. Colour on

You might think that colouring your hair is purely an aesthetic decision, but did you know that it can help make thin hair look thicker? Cleverly placed highlights and lowlights can add depth to fine hair, making it appear fuller. A good colourist will be able to advise on the best way to achieve this, so talk to your hair stylist about your needs and the overall effect you want. Just remember: coloured hair requires more care, so help keep it nourished with a weekly lightweight hair mask.

3: Go light on product

Sometimes it can be tempting to keep throwing product at thin hair to try and add some oomph, but too many gels and creams can really make fine hair droop. Try simplifying your styling regime with a lightweight mousse, like TRESemmé Beauty-Full Volume Touchable Bounce Mousse, which provides featherweight hold and helps give hair volume and lift without crunch. 

4: Perfect your blow dry 

Fine hair needs lift at the roots in order to create volume. The answer? A brush and your blow dryer. This is a tip we love: instead of parting your hair in its usual place to dry, try the four-way flip: brush all hair to one side and blast with your dryer, focusing at the roots, then flip your hair to the other side and do the same. Repeat this process both forwards and backwards.

Sound strange? Doing this helps prevent your hair from simply falling flat in its usual part, instead creating fullness all over. Continue drying your hair in all four directions until it's 90% dry – then use a round brush to lift top sections at the root and blast upwards for a volume boost to finish. Remember: use a heat protectant spray before blow drying to help guard against damage. 

5: Hold it 

You may feel wary of adding too much product to thin hair (see tip three!), but hair spray really does help fix that fresh-from-the-salon look. Lightweight formulations, like TRESemmé Salon Finish Extra Hold Hairspray, are non-sticky but strong, even in humid weather – so your style won't sag throughout the day. 

So, next time you're wondering how to make thin hair look thicker, remember these tips for tresses that are full of body and bounce!
