I thought I'd just point out to start off this post that I wash my hair about 3 times a week on average. I find this is all my hair needs and there's no point putting my poor, bleached hair through any more exposure to heat / chemicals than it needs! I also never use straighteners on my hair unless I need to. This helps the ends to stay in relatively good condition, as I'm a bit hairdresser-phobic and very rarely get my hair cut... tut tut.. I know!
Of course, the first two products are a shampoo and conditioner. I've used Tresseme Colour Fade Protection (renamed to Colour Revitalising?!) for probably around 4 years now - I find it conditions my bleached hair just the right amount so that it's not straw-like but not stretchy either (if you know what I mean?!). The 900ml bottles last forever! I think my last lot took me over 6 months to get through! I normally buy these in when they're on offer, but they're only £4.69 each at Tesco without any offer, pretty darn amazing for more than half a years worth of product!
I also mix in a small amount of the Pro:Voke Touch of Silver Twice a Week Brightening Shampoo (phew!) when I shampoo my hair. Probably twice a fortnight I'll shampoo with just this to reduce brassiness. They sell this for £2.50 at my local Factory Shop, but I used to buy it on Amazon for a similar price. It lasts me about 3 or 4 months.
Onto post-wash care. I guess the most important thing for anyone these days is heat protection spray. I've used Tresseme Heat Defence Spray for about 2 years now - this is the bottle I bought two years ago and it's still going despite using about 4 sprays each time I wash my hair. I still have about a third of the bottle left! I use it when my hair is damp. It's suitable for use with GHDs as it protects against heat up to 230 degrees (I've found this important to check if you use high heat straighteners / curlers, as some only protect up to 180 degrees etc). This retails at £4.69 (300ml) at Tesco and Superdrug.
I also use this Aussie Miracle Hair Insurance Spray. It's not the best leave in conditioning spray I've come across, but it's still a great product. It does make my hair more manageable. It's also lasted me a long time, after a years use I have a third still left. I spritz 4 pumps of this into my hair after using the Heat Defence Spray. This retails at £4.49 (250ml) at Superdrug.
Finally, I use Moroccan oil on the lengths and ends of my hair about once or twice a week max. I apply a couple of drops after using the sprays, then I'll leave my hair to dry off in a towel for half an hour or so before finishing it off with a hairdryer. As you can tell, it's a bit of a messy product, but it works a dream! You'll also notice it's not the real deal, well, not the 'real' Moroccan Oil brand! I spotted this in T K Maxx for £9.99 (120ml) - saving a bucket load on the branded oil! It's by Monica Olsen and I'd really recommend it. I've seen a few other lesser known brands' versions of Moroccan oil in TK Maxx too, so before you fork out on the real deal have a look in there to see if you can find any bargains. This has lasted me probably nearly two years now too and I have more than half left.
