I have been a long-term sufferer of over-processed, dry hair for quite some time (due to previous highlights, ombre and dye-jobs) so for years I've been on the hunt for an affordable product I can use without shelling out loads of cash on the expensive ranges always pushed by salons and hairdressers. 
So, you'll be more than happy to discover that after googling 'Gigi Hadid hair secrets' at the weekend, I discovered one of her stylists swears by the Salon Science ReCorrect Leave In Treatment, £15, for over-processed damaged hair, which lead to me rushing out to Boots at the weekend to grab a bottle. I also picked up the Shampoo and Conditioner in the same range while I was there because they're currently on offer at 3 for 2 so I couldn't say no to that.

After recently having highlights to blend away the ombre look I've had for the past year I was in need of a little TLC so after buying the Salon Science products I was more than excited to try them out. I washed my hair first with the Salon Science Retextuluxe Shampoo, £13 and Salon Science Retextuluxe Conditioner, £15 and found only a tiny amount of each is needed and instantly my hair felt clean and soft and the smell, which is grape, is so lovely!

I was most excited to try the leave-in treatment, as I think these are where you find the best results when it comes to hair care. The great thing about this treatment is the fact that it is a leave-in conditioner, you don't have to sit around with wet hair for 20 minutes while it works before getting back in the shower and washing it off and I love that. I used a small, chestnut-sized amount and worked it into my ends before using any leftover nearer my roots.

A lot of comments and reviews about this product are that it's too heavy or it's making people's hair feel too greasy. Personally, I didn't experience this at all when using the treatment and I can only imagine that perhaps if you do get that feeling then using a smaller amount and making sure it's worked fully into your ends only, steering clear of the roots, then you may notice a difference.

I then blow-dried and styled as normal, using my usual heat defence spray and my hair felt amazing afterwards, soft and silky despite the beatings it's taken recently from the highlights. The best thing about this treatment is that you can use it regularly and the bottle recommends at least twice a week so you may get through it a little quicker than some of those other intensive hair masks but the fact you're treating your hair to that luxury multiple times a week means you'll notice a difference much sooner.

OLAPLEX REVIEW: HAIR'S HOLY GRAIL

Well, Olaplex. Where do i begin?! If you've got color-damaged, dried hair then you're going to want to stick around for this one so grab yourself a cuppa and get comfy. I was heading to Leo Bancroft's Weybridge salon for a cut last weekend and knew I was in dire need of a treatment beforehand. Following a lot of salons and stylists on Instagram I was sure I'd heard of Olaplex before so when an Olaplex treatment cropped up on Leo's list of services I immediately asked my stylist Holly to book me in for a treatment before my cut.

If you haven't heard of Olaplex, let me give you the 101 on the sciencey-stuff. Most conditioners, even the expensive leave-in ones, usually just sit on top of your hair, temporarily treating damaged hair which can leave you with a silky smooth finish at first but after a few washes you're back to square one. This is wear Olaplex is different because it actually repairs and fixes the hair shaft while it colours and treats it. To give you some context, Olaplex is how Kim Kardashian went platinum from her natural dark locks in one day without going bald.

My Olaplex treatment was a two-part process and the whole process took half a hour from start to finish. The sensation was an odd one, the product is obviously a liquid but didn't feel super wet or thick like some conditioners so until I reached up and patted my hair it didnt' feel like there was any product on at all as it wasnt trickling down my neck or the side of my face which is always a bonus!

When it was rinsed out I reserved all judgement until my hair had been cut and blow-dried. When I finally ran my fingers through my previously thick, dry, damaged brittle hair I could have cried with happiness. That sounds dramatic but I've been through a few ordeals with my hair over the years and the last time I felt that silky-smooth, lightweight, freshly-cut hair feeling was probably about six or seven years ago. Since then, every blowdry has been a nightmare with hair breaking, brushes struggling to pull through the ends and stylists unable to run their fingers through my hair. It used to fall heavy, full of frizz and the ends looked frazzled.

Not now. The damage has literally been reversed and it's like I've rewound the last few years of bleach and dye, leaving my hair feeling so light and soft and genuinely healthy. I'm so excited that Olaplex is a thing and it doesn't cost a fortune either, my treatment was £30 and worth every single penny.

Olaplex can also be added to colour and bleach to minimise damage and if you YouTube Olaplex you'll find an abundance of videos showing girls with damaged hair going even lighter with little to no damage at all. It's incredible and a revolutionary product which hopefully will be rolled out to more and more salons around the UK - and the world - very soon!

Let me know either in the comments below or over on Twitter @laurenfell if you're thinking of giving Olaplex a try, I'm also happy to answer any questions you might have!

JEROME RUSSELL BBLONDE MAXIMUM LIGHTENING SPRAY

If there's one thing you guys should know about me it's that I am always changing my hair colour. Over the past year or so I've been various shades of blonde and ombre but now that autumn/winter weather is creeping in it's got me in the mood for something very different altogether.

Now, I knew that I didn't want to go even blonder right now - let's wait til next summer though, eh - actually, my goal wasn't to drastically change the colour of my hair but to even it out ahead of a whole new shade that I'm aiming for this season and the Maximum Lightening Spray* seemed ideal!

You use the spray after you wash your hair with a clarifying shampoo and after three applications you should see a gradual lift, even more so if heat is applied after use. Now, I can probably guess what you're thinking, yikes, a lightening product + heat = fried hair and I'm not going to lie, I spread out the three applications over a couple of weeks as the thought of frying my roots didn't appeal to me. However, I was pleasantly surprised by how soft my hair feels after using, although bear in mind I did only spritz this product closer to my roots and kept it entirely away from my ends.

I noticed a visible lift in colour after one application and this product by Jerome Russell definitely helped to even out the colour, giving me a much better base for my next colour which I'm very excited to be having done by the lovely Holly at Leo Bancroft's salon in Weybridge. I shall keep my plans under wraps until Tuesday 20th but if you follow me on Pinterest you can probably tell the gorgeous shade that I'm hoping to achieve *insert smiling devil emoji here*.

The BBlonde range is so extensive and I definitely recommend it if you're thinking of going blonde this season, however, if you're looking for something less intense then the Lightening Spray is the one to go for to enhance highlights or keep your ombre looking fresh. Team it with one of their awesome toners - either a natural shade or be daring and go for a pretty pink - for a completely finished look!

When you're not a natural blonde - like myself - it can be a struggle to keep your blonde looking fresh and to keep those annoying yellow tinged out of your hair.

There are a combination of ways to battle brassy blonde hair, here are some of my favourites:
