Hair shedding and hair thinning have been reported to be affected by dandruff and seborrhoeic dermatitis. The present study was conducted in 150 men presenting with telogen effluvium related to androgenic alopecia associated with dandruff. They were randomly allocated to three groups receiving each one of the three shampoos in the market containing either 1% ketoconazole (KTZ), 1% piroctone olamine (PTO) or 1% zinc pyrithione (ZPT). Shampoos had to be used 2-3 times a week for 6 months. Hair…

A Comparison of Clinical Efficacy between a Basic Shampoo with Herbal Extracts Containing Climbazole and Its Similar Sample Containing Piroctone Olamine in the Treatment of Dandruff and Seborrheic Dermatitis

TLDR
Both shampoos containing climbsazole or piroctone olamine beside herbal extracts are effective in the reduction of dandruff and relief of other seborrheic dermatitis symptoms but climbazole seems to be more effective than piroctorine in the treatment of d andruff.

Hair care and anti-dandruff.

TLDR
Hair-dandruf f relationship may conversely explain the absence of dandruff on bold pates, and applies equally to hairless or shaved sites and to regions that sport only vellus hairs.

Effect of residence time on the efficacy of antidandruff shampoos.

TLDR
The benefit of a residence time in treating dandruff is documented and the level of improvement in efficacy may vary according to the nature of the shampoo.

Efficacy and Tolerability of a Shampoo Containing Broad-Spectrum Cannabidiol in the Treatment of Scalp Inflammation in Patients with Mild to Moderate Scalp Psoriasis or Seborrheic Dermatitis

TLDR
Replacing current shampooing practices with a broad-spectrum cannabidiol-containing shampoo significantly reduces both severity and symptoms of scalp inflammation within 2 weeks, with excellent tolerability and treatment satisfaction in subjects with mild to moderate scalp psoriasis or seborrheic dermatitis.

An anti‐hair loss treatment in the management of mild androgenetic alopecia: Results from a large, international observational study

TLDR
Hair loss improvement and hair quality with AC5 once daily was assessed in 527 subjects with mild AGA in an open‐label, observational, international real‐life study and AC5 was well tolerated and highly appreciated.

TLDR
Data show the increased duration of yeast reduction for the ketoconazole shampoo over the two other formulations, which is explained by the combination of its antifungal and pharmacokinetic properties.

Androgen responsive genes as they affect hair growth.

TLDR
Results from this study indicate caspase 3 to be of primary importance in normal hair homeostasis and that DHT may be signaling greater expression of caspases, inducing apoptosis in androgenetic alopecia.

The response of seborrhoeic dermatitis to ketoconazole

TLDR
It is concluded that Pityrosporum yeast infection is the immediate cause of seborrhoeic dermatitis and that dandruff is its mildest manifestation.

The aim of this review is to determine the location and chronology of the microinflammation process within the complex pathophysiology of the human pilosebaceous unit in order to improve the possible approaches for the reduction or prevention of the development of AGA.
