causes for greasy hair

Oily dandruff:

Oily dandruff is a process that occurs on the scalp when yellowish flakes form and stick to the head of hair.


Our scalp produces greasy dandruff when we have:

  • Poor diet, chemical abuse.
  • Inadequate hair hygiene.
  • Psoriasis.
  • Stress. 

If we want to fight this condition, there are home remedies, but if it doesn’t work, you should go to a dermatologist.

 Some of these remedies are:

  • Lemon juice or its peel: make an infusion with the peel of a lemon and 200 ML of water. When it is ready, add the lemon juice. Apply with your fingers to the scalp and rinse with abundant water. 
  • Baking soda: mix a little water with two spoonfuls of baking soda until you get a homogeneous paste. Apply it to the scalp with a gentle massage, leave it on for 10 minutes, and rinse with plenty of water.
  • Apple vinegar: mix the vinegar with the same amount of water, apply it to the scalp and leave it on for 45 minutes.

Seborrheic Dermatitis:

Seborrheic Dermatitis is a disorder that affects the scalp producing spots, scales, reddish skin, and dandruff, consequent itching also can affect the eyebrows, face, sides of the nose, chest, and eyelids.


Some causes of seborrheic dermatitis are:  

  • Fungus present in the sebaceous glands called Malassezia.
  • Strange responses of the immune system.

To treat seborrheic dermatitis, we find the following:

  • Over-the-counter dandruff shampoo.
  • Applying creams with anti-inflammatory ingredients like hydrocortisonefluocinoloneclobetasol, and desonide is available by medical prescription.
  • Antifungal shampoo.
  • Mineral oil. Apply mineral oil to the scalp to soften and remove scales, leave it on for about an hour, then comb the hair and wash it.

  • Fish oil supplements such as Omega 3.
  • Apply aloe vera to the affected area.

Seborrheic Alopecia:

Seborrheic Alopecia is premature hair loss caused by excessive production of oil that induces and accelerates hair loss. 

That is because the sebum destroys the hair follicle and prevents it from breathing, so the hair begins to fall out little by little. 

 To avoid seborrheic alopecia, you must perform certain habits such as: 

  • Change your diet. 
  • Eat more fresh fruits and vegetables, also foods rich in vitamin B and zinc.
  • Drink more water.
  • Change your shampoo for one free of sulfates, parabens, and silicones 
  • Do not use dry shampoo or fixative products as they clog the pores.
