INTRODUCTION
Dandruff is becoming the major and common problem of hair nowadays. It is the condition that produces flakes on scalp skin, followed by itching on skin. Dandruff is a noninflammatory and chronic condition which is characterised in the most common dermatological skin problem, related to the scalp that is eminent by an excessive range of scalp tissue being affected [1]. The main cause of dandruff is not visible properly, but there are multiple factors such as, oily scalp, poor hygiene leading to fungal infection and it appears more often if the hair is not washed for a week. The use of dirty water and at poor families where anti-dandruff tools are expensive, it occurs frequently. A yeast-like fungus, Malassezia, feeds on oils on the scalps of most adults, dry skin, sensitivity to hair care pro-ducts or contact dermatitis, other skin conditions, such as psoriasis and eczema are also the causative factors behind dandruff. It causes embarrassment in public places and hair loss [2]. A high level of sebum occurs by dandruff on the skin in various areas. Its symptoms are redness, flakes, and itching of the scalp, hair breakage, and unexpected hair colour and skin discoloration [3].
The main two ways of dandruff treatment are using chemical-based anti-dandruff shampoo and herbal based antidandruff shampoo [4]. There are various shampoos and scalp preparations available in the market, against dandruff, which contain chemicals and which may cause certain side effects. The plant includes several compounds, which behave in a biological way against dandruff causing agents. Synthetic shampoos can cause side effects, like itching, irritation, loss of hair, nausea, headache and increased scaling [5]. The usage of these synthetics causes adverse effects, skin irritation, allergy, hair breakage, skin discoloration, unexpected hair colour and cancer [6]. In the Indian medicine system, various plants are used in the dandruff treatment as Brahmi, Bengal gram, Reetha, Hibiscus, Liquorice, Marigold [7,8].
These formulations are herbal based, with viable substitutes for synthetic drugs. Over the last few decades, natural products have shown a tremendous increase in herb based cosmetics. There are many herbal shampoos available nowadays, containing herbal ingredients like essential oils and extracts of plants. Many plants have beneficial effects on hair [9]. Traditional medicine in India is endowed with magical and religious beliefs and the World Health Organisation is engaged in setting up definite guidelines for appraisal of traditional medicine of major effectiveness [10,11].
Medicinal plants are rich in antioxidants, known to treat different diseases. The antioxidant potential is tested at various levels [12]. Preparations used in hair care are available in the form of creams, dyes, pomades, powders, tonics, etc. [13]. Hence, the knowledge from Ayurveda and herbals will be enhanced by information on the evidence-basis of these plants [14]. Drugs from the herb resources are quickly accessible, cheap, safe, efficient and rarely have side effects [15]. The need for herb based natural medicines is vastly increasing due to the lack of side effects and natural goodness [16,17]. The underlying research deals with the preparation and assessment of Poly-herbal anti-dandruff formulation containing the goodness of Amla, Bhringraj, Reetha, Hibiscus, Neem, Tulsi and Ginger.
