L'Oreal's guide to dying your hair red

Red hair colour – it’s fierce, vibrant and stands out in a crowd. From warm, orange-red hues to the boldest scarlet shade, there are so many ways to give your hair an edge.

Always toyed with the idea of going red but worried about maintaining those fiery hues? We’ve spent years honing our hair colour products, so vibrant, fiery and bright red hair is easier than ever to achieve.

Follow our guide on how to dye your hair red at home – from choosing your best shade, to the dyeing process and aftercare.

Which shade of red is right for me?

-For cool, rosier skin tones: Go for red-red or red-violet
-For warmer or olive skin tones: Choose red-red or orange-red. It’s best to stick to either two shades lighter or darker than your natural hair colour. This is more likely to give you a great colour match with your brows and skin tone.

How to dye hair bright red

Follow these steps to achieve beautiful, bright red hair with Colorista Bright Red Permanent Gel Hair Dye. If you don’t want to commit to a full head of colour, dip-dyeing and ombre techniques are a great way to get some subtle red tones. Make sure you are colour safe and that you do your allergy alert test 48h before colouring hair! You can do this by applying a small amount of the red hair dye and peroxide behind your ear.

Step 1

Red hair colour dyes better when you haven’t used shampoo for at least a day. Be sure to wear gloves, cover shoulders with a towel and wear an old t-shirt. Then begin by brushing out any knots and clip your hair up into two or three sections, leaving the bottom layer loose.

Step 2

Here’s a simple and great hack to make sure you don’t stain your skin: rub a thin layer of petroleum jelly around your hairline. Who wants pink blotches on their forehead? Not us!

Step 3

Remember to always follow the instructions on the packet. As a general guide (please refer to the Colorista Paint leaflet for more information) begin applying the mixture onto your roots and then apply the remaining product through lengths and ends. For even, all-over colour, it might be easier to get a friend to help you out. Repeat layer-by-layer, un-clipping hair as you go, making sure you’re coating every strand. Applying the dye can take between 10 and 20 minutes depending on the thickness of your hair.

Step 4

Once you’ve applied the red hair colour, secure your hair so it’s out of way. Remove any excess dye from the skin surrounding your hairline, then relax while you wait for the colour to develop. Go with the recommended time in the instruction leaflet, but check on it regularly to see how it’s progressing. We recommend waiting the full development time for the most vibrant, long-lasting colour. After all, good things come to those who wait!

Step 5

Time’s up! Wash your hair until the water runs clear and apply the nourishing post-colour mask included in the box. Leave the conditioner in for a while longer than usual to really lock that moisture into your hair.

Dyeing dark hair red

Brunette is an easy shade to transition from, providing the red hair colour you choose is darker than your current shade. The red hues in permanent dye are powerful and transform brown hair easily. Dyeing black hair red (especially if it’s been dyed black) isn’t recommended unless you see a hair colour professional who can bleach it first. Don’t want to go for a permanent shade? You could always try our Colorista Washout in red.

Dyeing blonde hair red

Blonde bombshells, it’s worth noting that rich, merlot shades of red could end up turning pink, which probably isn’t quite the look you were going for. Use the Colorista bright red shade, and make sure you keep up the fade-defying maintenance tips afterwards to keep your locks vibrant.

Our Colorista Bright Red Permanent Gel Hair Dye isn’t recommended for very light blondes, but rose gold could be your colour. Discover different rose gold looks here.

How to stop red hair fading

Red hair colour does have a reputation for fading fast. This can be explained by some simple science: red molecules are slightly larger than those found in other hair dyes, and the larger surface area stands less chance of clinging to your hair.

But it’s not all doom and gloom – following a colour maintenance haircare routine and investing in a good quality home dye kit are essential for maintaining luscious red locks. Colorista Bright Red Permanent Gel Hair Dye is expertly formulated to lock in colour, and by using Elvive Colour Protect products in your daily routine, your hair will look radiant for longer and get the nourishment it needs to stay looking fresh.

Three ways to take care of dyed hair - and make your colour last longer

1. Wait 72 hours before shampooing
Hair dye works by opening the cuticle layer of your hair and penetrating the hair shaft. And it can take up to three days for the cuticle to close again.

If you wash during this time, you'll also be washing your money down the drain, literally! The longer you wait between colouring your hair and the first shampoo, the better.

2. Use products specially formulated for coloured hair
If you dye your hair, it’s important to use hair products that are made to be used on coloured hair.

Most products will say if they are for coloured hair, but as if not just aim for sulphate free.

3. Use deep conditioner
Healthy hair holds onto colour for longer. A deep conditioner is the perfect product to repair dry, damaged hair. Just make sure it is a deep conditioner specially formulated for coloured hair!

How to thicken hair

Want to know how to thicken hair?

It’s one of the most common questions we get asked at the salon, and the answer to how to thicken hair is a complex one, but it can be done!

First it’s useful to understand a bit about why your hair loses thickness in the first place, and then read on to find out our top tips for how to get thicker hair…

What causes hair to lose thickness?

The most common reason for a gradual loss of hair in volume and thickness is getting older. This is because, as we age, the new hair emerging from the follicle is thinner, and eventually the same stem cells stop producing melanin (the colour pigment), so these wispy thin hairs turn grey or white.

Medical conditions like eczema can also make hair thinner, as it causes follicles to become blocked and prevent new hair growth.

Autoimmune and/or genetic disorders can also mean that hair gets thinner or even falls out altogether, while some meds can have an adverse effect on hair thickness.

Temporary hair loss or thinning hair can also happen after the body experiences a major shock that disrupts the hair's normal growth pattern.

What bad habits can cause thinning hair?

Before you can thicken hair, it's useful to know about any habits that might be causing it to thin. As we’ve heard, while genetics and medical conditions are sometimes responsible, they're not the only culprits!

Pulling at hair and keeping it in very tight hairstyles will, not surprisingly, gradually weaken the hair strand and the follicle it comes from.

Your lifestyle plays a major role in the quality of your hair. Stress and nutrition (vitamin deficiency) have been directly linked to poor hair quality, as well as unhealthy habits such as smoking and yo-yo dieting.

Four ways to thicken your hair's appearance

Try a spalp massage

When washing the hair, use your fingertips to massage the scalp in gentle circular motions to stimulate blood flow and promote the healthy growth of new hair.

Use hair thickening products

For thinning hair, we love L’Oreal’s Serioxyl Denser Hair Serum, a daily treatment to improve hair density. For fine hair needing a little volume boost, we recommend L’Oreal Serie Expert Volumetry volumising root spray, as well as Volumetry Shampoo and Conditioner. For long hair, suffering from thin ends, L’Oreal Serie Expert Pro Longer uses patented, filling technology to renew lengths and fills-in-ends. The Pro Longer Ends Filler Concentrate, is a weekly hair treatment that provides strength and durable thickness to ends.

Have regular trims

Have your hair trimmed regularly to prevent the development of split and uneven tips, which will cause the hair to look thin and straggly. Even, well-cut hair automatically looks fuller and healthier. Ask your stylist at Pankhurst and Deane about a micro-trim hair cut, or an 'invisible cut'. You get to keep the length but the split ends are dusted off.

Use a comb

When styling, use a comb to lightly tease the hair at the roots for instant natural-looking volume. Be careful not to damage the hair, so comb gently.
