I bought and used the Fibrology Thickness Booster up ages ago but wasn't particularly overawed. Luckily I got it half price at the time but didn't pick up any of the rest of the range, which may have been a mistake; I'll get to that later. So the idea is that this is a serum type of formula that comes in this tube with what looks like a handy "mixing lid"; you add it to your conditioner as an extra boost to help thicken your hair.
Firstly, while that lid seems like a great idea for mixing the serum into your conditioner, it's actually a bit awkward to use. You squirt the serum into your hand and then struggle to get the lid back on, while trying to add conditioner into your hand and not spill the serum everywhere. Gah! Not as much of a time saver as I expected although instead of whinging like me, you could just apply this to the hair on it's own and then add conditioner over that.
Only after I had started using it did I realise that suggested use is with the conditioner from the same range; I thought I could just work away and add it to my own conditioner that I was using at the time to give a volume boost but no, they expect you to buy a second product from the range to make the first product work better…eh, what now? That seems a bit much to me and had I realised that was the idea I probably wouldn't have bothered- I find that concept of trying to squeeze a bit of extra money out of their customers a bit icky to be honest. Surely the conditioner should work on it's own without needing an extra product to make it work better?
It also didn't make a huge difference to the actual volume of my hair, which makes me wonder if using the rest of the range would have led to better results, regardless of how annoyed I'd have been to have to buy two products when one on it's own should do the job.
While it's supposed to leave hair looking and feeling thicker with every wash for a cumulative effect (using revolutionary ingredient Filloxane apparently *sceptical face*), I only noticed the slightest of change on the first couple of washes and after continuous use until it was empty I can't say it made a huge difference to my naturally fine hair.
This may well be just me as I've seen other more positive reviews; my hair tends to be reluctant to respond to a lot of products designed to increase volume at the best of times. Available from Boots for €7.99 for 30mls, they currently have a 3 for 2 offer on if you're interested in trying it out for yourself.
Have you tried anything from the Fibrology range? Did you fare any better than me?
