When deciding to dye your hair with a box dye, you’ll see hair dye brands claim their products will last for X amount of washes, but how long does it take for hair color to grow out?
It will of course depend on the formula you’re using, and if you’re using a semi-permanent dye or a permanent dye, but keep on reading to find out how long your hair dye will stick around…
How Long Do Semi-Permanent & Permanent Hair Dyes Last In The Hair?
The formulas for semi-permanent hair dyes and permanent hair dyes are completely different. Using different types of colorants, which affects how long they last.
Semi-permanent hair dyes tend to last between 4 and 12 washes, and they tend to fade gradually with each wash.
When it comes to permanent hair dyes, they can last around 6 to 8 weeks before noticeable fading occurs.
It does depend on your hair type and your haircare routine, but with permanent hair dyes, you will have noticeable regrowth at the roots, as your hair grows.
To make your hair dye last longer, opt for color-safe shampoos and conditioners, as they’ll help keep your dye job looking healthy and vibrant.
It also depends on the type of color/shade you’re using, as red shades and pastel shades always fade faster due to their smaller color molecules,
I love dyeing my hair red, but I hate how quickly it fades and turns orange, so I can vouch for reds fading fast!
How Long Does It Take For Hair Color To Grow Out?
Hair typically grows around half an inch per month, but there are factors that influence the speed of hair growth.
When it comes to how long it’ll take for your hair dye to grow out, it usually ranges from 6 to 18 months, depending on your hair length, condition of your hair and the dye you used.
Factors Which Influence How Long Hair Color Takes To Grow Out
As I mentioned above, your hair naturally grows around half an inch per month.
If you used a permanent hair dye to color your hair, it will take longer to fade completely compared to semi-permanent dye, which gradually fades wash-by-wash.
Environmental factors, such as sun exposure and chlorine, can affect how quickly your dye fades.
How To Make Your Hair Color Grow Out Quicker
Having regular trims every 6 to 8 weeks is one of the best ways to grow your hair out quicker, as it removes colored ends.
Try to ensure you’re having a balanced diet that is rich in vitamins like biotin and omega-3 fatty acids, as they both promote faster hair growth.
Some people take supplements with both of those vitamins, to improve the health and condition of their hair (and nails).
Use deep conditioning hair treatments or hair masks at least once a week, to keep your hair healthy and hydrated.
Some haircare brands offer hair growth-enhancing products containing minoxidil or essential oils, and these supposedly help to stimulate your follicles for quicker hair growth.
You can also try reducing how often you use heat tools and chemical treatments on your hair.
Hot tools cause heat damage and breakage, and that can slow down your hair growth.
