ghd Rehab Fine Hair Thickener spray is a heat-activated leave-in treatment designed to provide an instant thickening effect for visibly fuller hair. Its advanced, lightweight formula for a strand thickening effect¹ works by increasing the diameter of each strand, resulting in instantly thicker and fuller hair².

Activated by heat and designed to work best with the ghd Duet Blowdry, or any ghd Helios Hair Dryer and ghd Hair Straightener, this treatment is perfect for fine or thin hair types. It plumps each strand while helping to maintain the hair’s natural condition, leaving it looking and healthier-feeling¹ with added body and bounce.

How to use:
Shake well before use. Mist generously onto towel-dried hair, focusing on the mid-lengths and ends. Comb through evenly, then activate by drying and styling with the heat of your ghd tools to reveal fuller, thicker-feeling hair.

What's inside:
Contains ghd Heat protection Biopolymer: Hair conditioning agent promotes hair density through hair growth.
Super Nutrient & Conditioning Complex: Provides conditioning for fine hair, and imparts gloss and shine, surrounding hair with a protective coating to help prevent future breakage.

¹Vs naturally dried fine hair.
²Consumer testing, Sep’23. 77% of 97 women agreed ghd rehab makes hair instantly thicker-feeling and 80% agreed it makes hair instantly fuller-feeling, vs before using rehab and heat styling.

APPLY TO WET HAIR

As the cuticles are 50% more open when wet, this will allow the product to deeply penetrate the hair instead of simply coating it. 

ACTIVATE WITH HEAT

With the application of heat from either your ghd Wet-To-Dry Tool or your ghd Helios Hair Dryer & ghd Styler, these formulas undergo a transition where ingredients become more fluid, effortlessly distributing throughout every strand penetrating the hair cuticle before sealing in essential benefits.

REVOLUTIONISE YOUR HAIR STYLING KIT

Unleash smooth, effortless blow-dries with ghd Rehab Fine Hair Thickener, infused with ghd heat protection, and ghd Duet Blowdry—or any ghd dryer and styler—to elevate your everyday styling routine.

PART OF THE GHD REHAB RANGE

Thanks to their heat-activated benefits, this range of powerful leave-in treatments improve hair condition whilst you dry and style with your ghd tool, for flawless results with no rinse or development time. ​

Fuller Hair in a Few Sprays

I have fine hair, and this spray is genuinely impressive. I use 1–2 mists on towel-dried hair after a shower, then brush it through and let it sit for a few minutes. I follow up by blow-drying my hair while running my fingers through it. The results are almost immediate. My hair feels noticeably fuller and more volumised, creating the appearance of thicker strands. Of course, it won’t grow new hair or increase actual hair density, but it does add significant body and helps eliminate that limp, flat feeling fine hair often has. This makes styling much easier. I’ve been using it daily for a couple of weeks now, and with just a couple of mists per day, I’ve used around 10% of the 95ml bottle. At this rate, it should last several months, which is great if cost is a factor. It does leave the hair feeling a little dry, but nowhere near as dry as styling powders I’ve tried in the past. The bottle itself is small, attractive and feels very sturdy, making it ideal for packing when travelling or going on holiday. The scent is also worth mentioning — it’s fresh and pleasant, without any harsh chemical smell. It actually smells quite professional or premium, which is a nice touch. I won’t comment on price, as I received this product as a free sample to test. What I can confidently say is: this product works. Pros: Adds instant volume and fullness to fine hair Helps create the look of thicker, more bodied hair Makes limp hair easier to style Easy, lightweight application (1–2 mists go a long way) Economical usage — long-lasting bottle Less drying than styling powders Fresh, pleasant, premium-smelling fragrance Attractive and sturdy packaging — travel-friendly Noticeable results from the first use Cons: Slightly drying on the hair (though better than powders) Doesn’t increase actual hair density Cost not assessed (as product was a sample)

Excellent Product!

This product is brilliant. As a regular user of the GHD heat defence spray, this one definitely did not disappoint. It has a really nice smell and does what it says, makes my shoulder length fine hair look thicker and from the very first use. I've had many compliments so this will definitely be a product I'll buy again and again. Give it a try, you won't be disappointed!

Amazing result

I received this complimentary from GHD in exchange for my honest review and it's great! I have really fine, flyaway hair and up to now nothing has tamed those pesky split ends. The bottle itself has a sleek elegant design in black and silver which would look great on any dressing table. You need to use this spray on towel dried hair, it does come out quite a bit so best to hold a bit further away from your head to distribute it a bit better. Comb through to the ends and style hair as normal. Now this is where the magic happens... My hair was fuller in appearance and no signs of any split hairs! The scent of this product is a lovely light floral and lasts in your hair all day. This is definitely going to become a permanent fixture in my haircare routine as my hair looks so much healthier now!

Game changer

I have naturally fine, flat hair that tends to fall limp within hours of styling, so I anm always on the hunt for something that gives me extra volume without weighing my hair down. The ghd Rehab Fine Hair Thickener absolutely delivered! From the first use, I noticed a difference. The product has a lightweight, almost creamy texture, and it spreads evenly through damp hair without feeling sticky or heavy. I used it before blow-drying (as recommended since it is heat-activated), and the result was noticeably fuller, bouncier hair that still felt soft and natural to the touch. What I love most is that it doesn’t make my hair greasy or stiff like some other volumizing products. Plus, the fact that it also acts as a heat protectant is a huge bonus — one less product to apply! My ends feel healthier, and my style lasts much longer throughout the day. Highly recommend this if you have fine or flat hair and want something that actually works without buildup or residue. A little goes a long way, so the bottle will last too. I love the scent of this too it is divine.

A product that works!

I have tried lots products to help my fine with little success, most work great the first couple of hours but then leave my hair flat quickly greasy. This thickener really did produce results, gave the heavier appearance I was looking for and my roots the volume it needed. I was pleasantly surprised that for the next two days I could still style and go with no greasiness. The smell is unique and really nice. I also like the packaging and size but would prefer it a lower cost (or bigger bottle). One star off as downsides for me is it gives a straw feel but thats what adds the texture / thickness and my hair get very tangled throughout the day, especially if slept on. I would recommend anyone with fine hair to try this product if nothing has worked for you in the past. I will definitely continue to use it.
