The Benefits Of Medicinal Herbs For Skin And Hair

Introduction

Both skin and hair reflect our overall health and this article discusses the importance of diet, optimal nutrition, and herbal remedies for boosting our inner health and enhancing the outer glow. If you are looking for natural remedies that enhance skin and hair health, medicinal herbs have many properties to support this. Read on for advice on choosing herbs for specific skin and hair problems such as acne and hair loss.

Brief anatomy and functions of skin and hair

Anatomy and functions of the skin

Both hair and skin, along with the nails, form part of the integumentary system which protects the body from the elements such as cold, heat, radiation, and infection. Part of the innate immune system, the integumentary system is composed of skin, hair, nails, glands, and nerves. Skin is the largest organ in the human body having a surface area of about 2 square meters and weighing 10 lbs. Skin is composed of two parts: a thin, outer layer (the epidermis) and the thicker, inner layer (the dermis).

Most cells of the epidermis are keratinocytes (90%) which produce keratin, a substance that protects the skin from sun rays, chemicals, and microbes. Around 8% of cells in the epidermis are melanocytes which contain skin colouring pigment melanin, melanin also absorbs ultraviolet (UV) light.

The dermis consists of two layers of connective tissue which contains collagen, elastic fibres, blood vessels, nerves, glands, and hair follicles. A natural oil known as sebum is produced by the sebaceous glands which keep the skin supple and moist, whilst sweat, which cools us down, is produced by the sudoriferous glands.

The skin has the following functions:

  • Thermoregulation - temperature control
  • Protection from abrasion, infection, radiation
  • Cutaneous(skin) sensations
  • Synthesis of Vitamin D
  • Wound healing

Anatomy and functions of the hair 

The whole surface of the human body is covered with hair consisting of two types: short, fine hairs called ‘vellus’ and thicker, longer hairs known as ‘terminal’.

Hair has a shaft and a root, the shaft is the visible, external part whilst the roots are deep in the skin surrounded by the hair follicle (skin that connects to the sebaceous gland).

New hair cells are made at the base of the hair in the bulb where the papillae are found. Papilla supplies blood to the hair root and new cells are made in the bulb causing hair growth.

Hair functions include:

  • Protection from external environmental factors such as sun
  • Production of sebum, sweat, and pheromones
  • Temperature regulation

Diet and lifestyle factors for skin and hair 

Exercise benefits all physiological functions and hair and skin reflect our general health. Benefits to our cardiovascular system will promote better circulation providing nourishment to the hair and skin. Reducing stress and getting adequate sleep will also benefit hair and skin health, as will good personal routines around skincare and haircare.

Diet is vital to healthy hair and skin and having nutritional deficiencies will result in hair and skin problems. Following a balanced and nutritional diet is the key to skin and hair health. This includes adequate proteins, fatty acids, vitamins, minerals, and more importantly water for optimum hydration. 

According to the British Dietetic Association (BDA), the following are vitamins and minerals important to maintain healthy skin.

  • Vitamin A
  • Vitamin B2
  • Vitamin B3
  • Vitamin B6
  • Vitamin C
  • Vitamin D
  • Vitamin E
  • Zinc
  • Selenium

In addition, Biotin (Vitamin B7) and haematinics (Iron, folic acid, and Vitamin B12) are particularly beneficial for healthy hair.

Including omega-3 fatty acids in the diet, with food sources such as low-fat dairy, nuts, pulses, fish, and lean meats, ensuring optimal gut health by increasing the variety of fruits and vegetables, and consuming probiotic and prebiotic foods will greatly enhance hair and skin quality.

An overview of herbs for skincare 

Medicinal herbs can be used to improve physiological functioning generally. Adaptogens are a class of herbs that act to maintain homeostasis by reducing the damaging effects of stress on the body. Such herbs have the capacity to enhance all systems, which will reflect in skin and hair.
