How To Use Pro Tips Ingredients

To create the best blank canvas for your color, we recommend that you first lighten your hair with our easy-to-use GDY Lightening Kit. Our semi-perms work best over pre-lightened hair, levels 7-10. Please refer to individual colors for the best starting level.
Squeeze your color into a plastic bowl. Remember: wear gloves to prevent staining on your hands.
Do a strand test before applying the color all over your hair to ensure you love the look.
Divide your hair into 4 equal sections and apply dye directly onto dry hair with a color brush or your fingers. Make sure the color is fully saturated throughout each section by applying a dollop of color for every two inch portion of your hair. Gently emulsify/massage into the hair to ensure coverage.
Let the color sit on your hair for at least 30 minutes.
Rinse with cool water.

To maximize the vibrancy and longevity of your newly dyed hair, we recommend waiting at least 24 hours before your first shampoo. When it is time to wash, use cool water and a color-safe shampoo and conditioner. Washing less frequently can also help extend the life of your color.
Blue Ruin is a highly pigmented, long-lasting blue that will gradually fade into lighter shades of blue over time.
Blue Ruin can add a blue tint to darker hair and will appear most vivid on level 7+ hair.
Because Blue Ruin is one of our most highly pigmented shades, some bleeding or color transfer is normal, especially when the color is fresh. For the longest-lasting results, wait at least 24 hours before shampooing. However, if you experience excessive bleeding or transfer after your initial rinse, you can shampoo sooner to help remove excess pigment. Keep in mind that shampooing immediately may result in some additional fading, so we only recommend this step if bleeding or transfer is a concern.

BEST BLUE EVER

"if blue is your color, use this one. It’s the best I’ve ver tried always comes out even and last for so long and doesn’t fade muddy or green!"

— Saria (5/5)

Best blue dye out there

"This color is genuinely the prettiest blue i’ve ever used. it doesn’t stain the skin bad, it doesn’t fade much at all, and it is so beautifully vibrant. been using this shade for about 3 years now. it’s also super conditioning, as i’ve bleached my hair multiple times within two weeks and used this brand and never had any breakage. pro tip: if your hair bleaches super yellow (like mine), mix a little bit of Ppl Eater (the purple shade) into your blue. pics of my hair freshly colored vs about 2 months later!"

— Alicia (5/5)

Q&A

Hi GDY, Loved this hair color but I'm kinda ready to move on to a Peach tone from your brand as well. My question is: Do I have to use a color remover first? And do you have one in your brand? Or could I just apply the lightening kit directly? Thanks!: When covering blue with peach, we recommend doing a test strand. Take a pretty small section of the faded color, and lighten it with our Lightening Kit. After you’ve rinsed it out, and waited for your hair to dry, apply the new color and see if it’s the desired result. You can always send us a photo of your current faded color to help@gooddyeyoung.com and our color expert can take a look for the best recommendation.
Will it cover faded purple tones?: Hi Diana, Thanks for reaching out. Depending on the purple tones, it will cover most of the purple, with a final result expected to be a slightly purple-esque blue! Think of a dark smokey periwinkle. Our color expert can give you custom feedback if you're able to email a photo of your hair to help@gooddyeyoung.com. Team GDY
What undertones does this dye have as I’m worried my hair would turn green as it fades: Hi Shantel, Thanks for reaching out. Blue Ruin is a true-blue tone, with slightly teal undertones. If your hair has any golden tone, you may have a slightly different final result than true-blue (which is why we recommend pre-lightening for best results). Our color expert can give you custom feedback if you can email a photo of your hair to help@gooddyeyoung.com. Team GDY
Hi. I’m just wondering if I used the lightening kit over my pink hair just now, would the blue still take over that? Just before I buy it and it doesn’t come out correctly 🤣 many thanks in advance x: Hi Alicia, For the best advice we would recommend reaching out to our customer service team at help@gooddyeyoung.com
Do I need to have freshly washed (shampoo'ed) hair? Or can I have washed and conditioned prior to using on dry hair?: Hi There, We would recommend using over freshly washed hair
