Effectiveness of Tai Chi vs Cognitive Behavioural Therapy for Insomnia in Middle-Aged and Older Adults
November 27, 2025
Background
Dandruff is a common scalp disease which affects about 50% of people at the age of puberty, without any preference to gender or ethnic background. It is a common problem that every person in different parts of the world faces some or the other time in his or her lifetime. The word ‘dandruff’ is derived from the Anglo-Saxon words ‘tan’, which means ‘tetter’ and ‘drof’, which means ‘dirty’. Dandruff affects the quality of people’s appearance and is known to cause itching most of the time. Other studies have pointed out that the keratinocytes mainly participate in the immune reactions that are commonly associated with dandruff. Dandruff in most cases is known to be seasonal and tends to be severe especially during the winter season.
Epidemiology
Dandruff is very widespread; up to 50% of adult population around the world is affected by it. This is more common with males than with females. It usually starts during adolescence and can be most active in the early adult years with an average age of 20 years, and it decreases in frequency and severity after 50 years of age. It has also been established to manifest differently across different ethnicities; for example, a survey undertaken in the U. S and China determined that 81 to 95% of the African Americans, 66 to 82% of the Caucasians and only 30 to 42% of the Chinese suffer from dandruff.
Anatomy
Pathophysiology
Dandruff is associated with enhanced scaliness; scaliness is the normal rate of shedding of skin cells of the scalp, which during dandruff episodes may be as high as 800,000/square cm compared with the value of about 487,000/square cm observed after washing with detergent. Nevertheless, this marked shift in the rate of keratinocyte proliferation does not change the classification of dandruff as a non-inflammatory disease. The detailed processes that take the normal cell shedding to the extent observed in dandruff are not yet understood.

Role of Antifungal agents
Role of Anti-proliferative agents
Coal tar: It is widely used in anti-dandruff shampoos and is a clear example of this class of therapies. These include over 10,000 chemical compounds that will aid in suppression of bacterial growth and rejection of inflammation. This treatment is mainly employed in eradicating the symptoms of dandruff in the human body.
Role of Keratolytic agents
Salicylic acid: It is classified as a keratolytic agent and is applied to relieve dandruff conditions. Salicylic acid aids in the process of shedding the outside layer of the skin which means it aids in the removal of skin debris found in the scalp. It helps to prevent the visibility of the flakes which are characteristic of dandruff by encouraging the shedding of the outer layer of the scalp.

Managing dandruff involves a phased approach:
Acute phase is characterized by rapid control of symptoms with shampoos containing ketoconazole and selenium sulfide, as well as topical steroids with rigorous washing.
Transitional Phase prevents any flare ups by minimizing medicated shampoos and incorporates mild ones, continues with the scalp exfoliation added to this are changes in some aspects of lifestyles such as stress and diet.
Maintenance Phase focuses on avoiding relapse, using the mild medicated shampoos on a regular basis, proper scalp care, flare-ups identification, introduction of home remedies and constantly visiting a dermatologist. This strategy minimizes medium and long-term control and hair scalp problems effectively.
Medication
Apply sufficient quantity of lotion on the scalp topically one time daily for a week
Apply the lotion on the affected area, allowing the lotion to remain on the scalp for half hours
Shampoo 1%: Apply and repeat between 3-4 days 8 weeks
For 13 to 18 years old:
Apply sufficient quantity of lotion on the scalp topically one time daily for a week
