When Radhika started Adhik, the decision to use natural dyes was not a marketing choice. It came from a straightforward question: if we are making clothes that sit against your skin all day, what exactly are they dyed with?
Most clothing in the world is dyed using synthetic azo dyes. These are petrochemical compounds, engineered in the 1800s to produce consistent, fast, cheap colour at scale. They work. But they also include compounds that are known skin irritants, and in some cases, known carcinogens. They wash out into waterways. They sit on your skin from the moment you put the garment on.
What natural dyes actually are
Natural dyes come from plants, minerals, and organic matter. Indigo from the indigo plant. Madder from roots. Turmeric from the kitchen. The same materials that have been used to colour fabric in India for centuries before synthetic chemistry arrived.
The process is slower and more labour-intensive than synthetic dyeing, which is part of why most fast fashion brands avoid it. The fabric is first treated with a mordant, usually a naturally occurring mineral like alum, that helps the dye bond to the cotton fibres. Then it goes into a dye bath made from the chosen plant material. The whole process can take hours.
This is why two shirts from the same batch of Adhik cloth are never perfectly identical. The colour you get is the colour that happened, shaped by the temperature of the water, the concentration of the dye, and the specific fibres in your piece. We treat this as a feature, not a flaw.
Why organic cotton is the right base
Natural dyes work best on natural fibres. Organic cotton is grown without synthetic pesticides or fertilisers, which means the fibre is cleaner before the dyeing even begins. Conventional cotton uses roughly 16 percent of the world's insecticides despite covering only about 2.5 percent of global cropland. Those chemicals do not disappear after harvest. They stay in the soil, run into waterways, and remain in the fibre in trace amounts.
When you combine organic cotton with plant-based dyes, you get a garment that has no synthetic inputs at any stage of production. That is genuinely rare in clothing sold at accessible price points.
How the colour changes over time
Natural dyes age differently from synthetic dyes. Synthetic colours tend to fade unevenly and look worn-out. Natural dyes fade more gradually and more uniformly, softening over time in a way that tends to look intentional rather than tired. A lot of people find their Adhik shirts more beautiful after six months of washing than they were on the day they arrived.
To slow that fading, wash in cold water and dry in shade rather than direct sunlight. Avoid harsh detergents with bleaching agents. The colour will last considerably longer than most people expect from a naturally dyed garment.
The honest truth about the limitations
Natural dyes cannot produce every colour that synthetic dyes can. Certain brights, neons, and some specific greens are not achievable with plant-based dyes at all. The palette of naturally dyed clothing tends toward colours that exist in nature: the ochres, terracottas, pinks, blues, and greens that come from plants and minerals.
We think this is actually a good constraint. The colours available in natural dyeing are colours that work well together and work well on human skin. The restricted palette is part of what gives Adhik its visual coherence across collections.
Every piece from Adhik is small-batch, hand-dyed in Jaipur. When you buy one, you are buying something made in a process that has been practised in India for centuries. Not as a marketing angle. Just as a fact.
