Wash your hair less often and with cooler water. Colour will always fade slightly with every wash, but warmer water opens up the hair cuticles and lets out colour. (An extra benefit – washing bleached and dyed hair, which is usually drier, less often will also better preserve your natural oils.)
The reactions which produce the dyes are carried out at an alkaline pH, and in many cases this is provided by the presence of ammonia in the formulation. The ammonia causes the cuticles of the hair to swell, which then allows the dye molecules to pass into the hair and induce permanent colouring.
To make your own henna hair dye, mix about one cup of henna powder with 2 cups lemon juice. You can also add in a tablespoon of vinegar to help release the color. Allow to sit about 4-6 hours until it thickens. Apply to hair and comb through.
Heat will open the hair up and allow dye molecules to escape easier. Conversely, cold water helps seal the cuticle.
Adapt your washing routine.
Extremely hot water can strip your hair of color, so we always advise color clients to use warm water when they shampoo and cooler water when they condition to decrease fading. Water at cooler temps seal the cuticle, so that it can hold the color longer.
The vinegar actually helps the hair dye to remain bonded to the hair, according to my awesome stylist Viviane of Marina Beach Hair. Shout out to Viv, woot! 3. After using hair dye, wait 72 hours before washing.
Using ingredients like henna, indigo, coffee, tea, beetroot, carrot juice, lemon juice, sage, and walnut shells can help you achieve a range of hair colours while nourishing your locks. With patience and regular application, you can enjoy vibrant, chemical-free hair colour that enhances your natural beauty.
To achieve a permanent color, many hair dyes work using a system of ammonia (or ethanolamines in the case of some ammonia-free products), hydrogen peroxide, and p-phenylenediamine.
As a general rule of thumb, darker colors tend to stay on the hair for longer. So, if you're adding lowlights, a root shadow or all-over depth, the shade will offer more mileage than, for example, light blondes, light browns or light reds. The same goes for pastel colors versus rainbow colors.
No, you cannot keep a mixture for a future application.
It works by opening up the hair cuticle to allow the hair dye to deposit the permanent colour, meaning it'll completely replace your natural hair colour. Permanent will give you the best grey coverage so if you're worried about those pesky greys showing up, this is an excellent route to go down.
Conditioner is best paired with non-developer-based semi-permanent and direct dyes, as when used with permanent or developer-based dyes, conditioner can interfere with the chemical reaction and oxidation process required for lasting color, potentially resulting in uneven or inconsistent coloring.

Though they're a splurge, the products earned the best score for preventing hair color from fading over a month of simulated wear. They also came out on top for making color look shiny, richer and more vibrant.
What Is Permanent Hair Color? With permanent hair color, you'll find the real deal: chemical processing—or oxidation. Ammonia and hydrogen peroxide act together to open up the cuticle, interact with melanin and keratin (those are responsible for color and texture), and change the structure in order to deposit dye.
To preserve hair dye, use products specifically designed for color-treated hair, wash your hair less often with lukewarm water, avoid heat styling, and use hydrating treatments regularly to maintain moisture and vibrancy.
Some of the most common bad effects are dryness, fading, spots on the head, allergic reactions, uneven coloring, and allergic responses to the dye. Follow the advice exactly, do a patch test, moisturize your hair, limit how often you use it, and protect your head and face to lower the risk of side effects.
So in short, yes, using apple cider vinegar can help set and preserve your hair color's lifespan.
