Wavy hair tends to take on an “unkempt” or “stringy” look because there are sections of hair that grow in a similar wave pattern which will cling (clump) together, but may not curl in a 3-dimensional pattern. The curls may appear only below your ears or shoulders, but the clumps begin above that.
Instead of giving in to the comb, weave your fingers into your waves from beneath and give those waves a shake with fingers on scalp. This separates the clumps a little, but doesn’t destroy the wave pattern completely. This can be done standing upright or bending forward.
