If hair health is super important to you and you still want your hair to grow perfectly silky and smooth, then you might want to look at an ammonia-free dye like L'Oréal's Casting Creme Gloss. This just means they're longer-lasting but still gentle on your strands - and we can all do with that.
If you don't have the dough for expensive hair treatments, don't worry. After dying your natural hair - and even if you're looking for hair dye for dark hair - make sure to treat your hair with plenty of hair masks and leave-in treatments.

What should I look out for when buying red hair dye?
This may sound obvious, but for starters, you need to decide whether you want a permanent or semi-permanent 'do. Are you certain this is the colour you want to sport over the next couple of months. Or do you just want a temporary 'break over'? And, as we've already mentioned, you need to factor how much you value your hair's health into your permanent vs. semi-permanent dye decision.
Next up, which tone should you go for? Well, obviously, you being the decision maker here, you can choose whatever colour you so desire. That being said, here's our advice:
If your skin has warm undertones, then keep an eye out for coppery reds.
If your skin has cool undertones, try to look for red dyes with bluey hues. For example, a burgundy or purply red.
And, the third option, if your skin has rather neutral tones, well, the world is your oyster, so get experimenting!
What colour can I dye my hair?
Taking the plunge with a permanent red hair dye can be scary, to say the least. But you can always have a go with a semi-permanent dye first. Once you're happy with your colour, you can commit to the permanent a few months down the line.
From silver hair dye to black hair dye to even orange hair dyes (hey, if Olivia Bowen can rock it, so can you), there's quite the array of box dyes to choose from. But, chances are, if you've landed on this page, you've probably got your heart set on a certain rouge-y shade already...
Whether you're looking for a bright red hair dye or a dark red hair dye, worry not because there will be an option for you. But you should also look out for which dyes are best for your hair long term.
Is red hair dye damaging?
Annoyingly, the answer to this question is...it depends. Essentially, the thing about dying hair that can be damaging is using peroxide to strip away your natural colour.
When it comes to using a red dye, if you're a natural platinum blonde, you probably won't need to lighten your hair before you start. So, in this instance, it's likely that the darker red dye won't significantly harm your hair.
By contrast, if you're a natural brunette, you might want to lighten your hair using a blonde hair dye or bleach. Use this before you start the dying process to maximise your chances of achieving a vibrant red. In this case, your hair will probably be in a much weaker condition before you even apply your dye, thus increasing the possibility of damage.
But remember to check the ingredients on a dye before you use it, as some/most permanent dyes use peroxide.
The solution? Semi-permanent dye. Again, always check the product's ingredients list, but generally, semi-permanent dyes are peroxide-free. This does mean they might not be as effective, but it's a worthwhile factor to consider when picking your dye.
Is red hair high maintenance?
In short, yes, but there are ways to extend your colour's life.
Prolong your first post-dye wash for as long as possible and minimise your hair washing long-term. Yep, Manic Panic advises its customers to use dry shampoo as much as possible to avoid washing colour from the hair's cuticle.
If you can bare it, try washing your hair in cold water (when you do wash it) to avoid further swelling of the hair cuticle. Also, use baby shampoo; it's neutral (neither acidic nor alkaline) and will help minimise loss of colour. Even better, you can alternate this with shampoo for red hair to keep your tones as fiery as possible.
If you're sick of your red hair and want to move on from your red-head era, using a colour-stripping shampoo can work wonders.
What red hair dye do the celebrities use?
Chatting to heatworld as part of their Self-Care Sunday series, Strictly Come Dancing dancer Dianne Buswell revealed that she actually achieves her incredible crimson locks AT HOME.
She said, "In terms of colour, it's actually not as high maintenance as everyone thinks!" Gasp. Tell us more.

She continued, "I found a colour that I put on my roots, and it's the L'Oréal Professionnel Majirel Mix Permanent Hair Colour. I just put that on my roots myself, I don't need to bleach anything. I just put the colour straight on and then rinse it off, and it's red."
We love this product because it's for professional use in salons up and down the UK. Therefore, you know it's going to do a fantastic job. At just under £15, you can save yourself heap loads of money by doing your hair colouring at home.
And there you have it! Go shop Dianne's bargain hair dye now (before it sells out)...

She finishes off her colouring routine with this: "Then on the ends of my hair, I never actually put colour, I just put this conditioner that has a red tinge to it."
We recommend if you're not a natural redhead, colour the whole head of hair red on your first round, and then follow Dianne's method and use a red-coloured conditioner or hair toner going forward.
Dianne also shared that to protect her hair from constant heat from touring (you gotta get those curls just right for the crowd), she gets a "Great Lengths Keratin Bonds" treatment for her hair. "A lady called Vicky from Larry King does for me. I've been going to her for years now." She continued, "I find that the extensions almost coat around my natural hair, so it gives it that little barrier."
"So that's how I protect my actual natural hair, and actually, underneath, my hair has grown so much from having these bonds, which is amazing. Sometimes people don't even notice now when I have them in and when I don't, so that's definitely a good thing."
