How to Apply Onion Oil on Hair?

  1. Onion oil has a tendency to harden and thicken when exposed to cold temperatures. As a result, before using, reheat any solidified onion oil in the microwave or on the stovetop at low heat until it becomes liquid again.
  2. Divide your hair into small sections and massage the onion oil into each section, starting at the roots and working your way to the ends. Use a wide-tooth comb to ensure that it is evenly distributed (and to prevent tangles). To make it more comfortable, massage it with the tips of your fingers.
  3. There is no need to apply more oil to your hair after a sufficient quantity has been applied. Rather, evenly use your existing hair oil to fully cover each strand. More oil means more washing, which may deplete your hair’s natural oils and hydration, leaving it dull, brittle, and dry.
  4. Once you’ve covered every strand of hair on your head, twist it into a bun and wear it in a high bun to finish the look. Over-tightening ponytails, according to trichologists, may damage the hair’s roots and cause it to break when the ponytail is weighted down.
  5. Taking a steamy shower may be beneficial since the steam increases nutrient absorption. A warm cloth placed over your head may also be helpful.
  6. If necessary, lather up numerous times to fully eliminate all traces of oil residue.
  7. Finally, thoroughly rinse your hair with lukewarm water.
