Powder-based herbal hair colour can leave the hair feeling dry, tangled or frizzy, and some hair types notice this much more than others.
The important point is that dryness after herbal colouring is not necessarily evidence that one particular herb has failed or that every user will have the same experience. The physical nature of applying powders to the hair is itself part of the explanation.
Why powders can leave hair feeling dry
A practical observation I make is that powders tend to take moisture from the hair. Apply powders to the hair and it can feel drier, more tangled and more frizzy afterwards.
Henna can add to this effect. It is a strong natural pigment, but it can also leave the hair feeling dry.
This is why the experience can differ greatly between people even when they use the same type of product.
Curly and frizzy hair may notice dryness more
Someone with naturally curly, frizzy, rough or already-dry hair may feel the drying effect much more strongly than someone with silky hair.
That does not mean silky hair and rough hair necessarily take colour in the same way. In fact, there is an interesting trade-off: rough, dry, porous or frizzy hair can sometimes hold herbal colour more strongly, while very silky hair may develop a less intense colour.
So two observations that appear contradictory can occur together:
- the hair can feel drier after colouring; and
- the same rough or porous hair can take the colour particularly well.
Aftercare depends on the type of colour used
The natural two-step system and a chemical-containing herbal dye are not treated identically after colouring.
With the natural system, the initial approach is to rinse rather than immediately shampoo. Once the hair has dried, oil can be applied to the scalp and along the hair length, with shampooing following later. The oil is used to improve softness and is also described as helping the colour settle.
A chemical-containing hair colour requires different aftercare. The colour should be thoroughly rinsed away and shampoo used so that the chemical colouring material is not left sitting on the scalp. Conditioner can then follow. The useful takeaway is to expect that powder-based herbal colour may make some hair feel dry, particularly curly, frizzy or rough hair. Appropriate aftercare is therefore part of the colouring experience rather than something to consider only if a problem appears.
