Correct answer: Keratin
Keratin is a fibrous protein present in hair, nails, wool, and feathers. It is
different from other proteins as it is high in cysteine, which is an amino
acid containing sulfur.
This gives keratin a unique protective property and strength. Eating eggs, onions, sweet potatoes, salmon, sunflower seeds, mangoes, garlic, kale, and carrots can ramp up your keratin production.
Correct answer: Dermis (middle layer)
Hair follicles are tunnel-shaped structures present in the dermis (middle
layer) of skin. They are composed of 20 distinct types of cells.
Each type has a unique function. Hair follicles produce hair through a complex collaboration between neuropeptides, hormones, and immune cells.
Correct answer: Melanin
Melanin is secreted in the body to create pigment of hair, skin, and iris of eyes. Melanin also protects skin from harmful ultraviolet rays of the sun.
When you expose your skin to too much sun, your skin darkens to give you a tan. This is actually skin’s natural defense mechanism of producing more melanin for protection.
Correct answer: Palms and soles of feet Palms of hands and soles of feet have no follicles present, so there is no hair production. The rest of the skin has hair, either coarse or fine.
Correct answer: 1 cm
As per the Trichological Society, the rate of hair growth varies between races, ethnicity, and overall health of hair. It could be as less as 0.6 cm per month or as much as upto 1.7 cm per month.

Correct answer: Lupus

As a result, body’s own cells think follicles to be invaders and attack them.
Correct answer: Dihydrotestosterone or DHT
The enzyme 5-alpha reductase produces dihydrotestosterone (DHT) from testosterone in men. In women, the enzyme produces DHT from DHEA. DHT’s actions in the body and sensitivity of follicles to DHT can trigger hair loss, which is called male or female pattern baldness.
As per estimates by the National Institutes of Health (NIH), about 30 million women and 50 million men suffer from DHT-induced hair loss.
Correct answer: Yes
It is seen that hair color of bodies buried change. Hair possess a blend of black-brown-yellow eumelanin pigment and red pheomelanin pigment. Eumelanin is less stable and breaks down quicker than pheomelanin when oxidized.
Bodies buried in ice or sand show slow change of hair color, as they are in dry oxidizing conditions. Bodies buried in plaster or wood coffins show faster color change, as they are in wet oxidizing conditions.
