What is greasy hair?

Opposite of dry hair is greasy hair. It is when your scalp excessively produces natural oils that make your hair too glossy and oily.

What is dry shampoo?

This kind of shampoo is specifically used for greasy hair. It has a starch component or alcohol that helps absorb and eliminate sebum, the natural oil produced by the scalp (as mentioned as well earlier) making the hair look greasy or oily after a day, two days or more of no washing. Best dry shampoo brands, like Keranique, offer several hair products to resolve this hair problem. It usually comes in as a powder or a spray-on.

How dry shampoo works?

Dry shampoo, as it was named, can be applied to your hair even if it is dry. It is generally applied or sprayed on the head’s crown and areas where oils may be visibly collected. It does not need to be washed out like your conditioners and shampoos.

Aside from reducing the unattractive greasy hair, it also helps in cleaning your hair, retaining its fresh look. Here are the steps in using this hair product the right way, without causing further damage to your greasy hair:

  1. Make sure your hair is dry (not wet)
  2. Spray your hair, over the crown and not the scalp, but it should be six (6) inches away.
  3. Spray only the areas that are greasy or oily.
  4. Massage your scalp so to evenly distribute it, perfectly blended, reaching the roots.
  5. Do not use daily for a week, but just two days in a row.

  • When doing an updo, it keeps hair pins/bobby pins in place.
  • Delivers nutrients to your hair.
  • Gives fresher look after a workout or exercise.

What to Avoid in a Dry Shampoo?

  • Too heavy or strong formula – if your hair is not too damaged, practically fine, and is still a virgin from dye and treatment, opt for the lighter formula.
  • Sogginess or dampness – if you feel this after using dry shampoo, then you should try another formula that would best fit you.
  • Gunky buildup or residue – it should not leave anything behind once applied, so be sure that it absorbs quickly and completely.
  • An unpleasant smell – some people respond differently to some fragrances. If applied and it does not suit your sense of smell, then you should look for a better-smelling scent.

Other Ways to Fix Greasy Hair

  1. Natural oil remedies – Apple cider vinegar can control the scalp’s oil production by helping in restoring your scalp’s pH. Tea tree oil, on the other hand, can help cleanse the scalp and holds antifungal properties.
  2. Diet and lifestyle change – Eating food rich in Vitamin B2 and B6 can help reduce your sebum production. This would also mean you should cut out greasy or oily foods and eat more fruits and vegetables.
  3. Switching up your combs and brushes – Using the right brush can help in removing and distributing some of the hair oils so your hair roots will appear less greasy.
  4. Lemon juice and aloe vera – when mixed, the mixture will act as an astringent which helps in sebum production control and would also make softer hair.
