The growth cycle of hair 

An average, hair grows 1.25 cm (½ inch) per month. It is also estimated that on an average we lose 80-100 hair a day. A single strand does not grow continuously throughout its life. 

The stages of the life cycle of hair are: 

1.anagen 

2. catagen 

3. telogen 

4. Exogen

1. Anagen 

During the anagen phase, the hair follicle is active and the hair is growing continuously. New hair in early anagen grows faster than old hair, the average growth being 1.25 cm per month.

2.Catagen 

The next phase of the hair growth cycle is called as ‘catagen’. During this cycle, hair follicle undergoes a period of change and do not grow. This phase lasts for about 2 weeks. New cells are formed. At any time only about 1% of follicles are in the catagen stage.

3. Telogen 

This is the period of rest for hair follicles. This stage lasts for about 3-4 months. Approximately 13% of the follicles are in the telogen state at any one time.

4.Exogen 

After the resting period, follicles begin to lengthen. When the follicle reaches full length, a new hair begins to grow.

For normal goods, law of demand states the Indirect  relationship between price and quantity of goods.

In variable proportion production function, proportion of factors utilised changes because in short-run, all factors cannot be changed. Those factors which cannot be changed due to short period, are called fixed factors. Few factors of production are variable in the short-run- Capital, Capital goods, land, production technique, etc. are mainly fixed factors or remain unchanged in short period while labour units are variable. Size of plant also remains unchanged in short-run-In this way, few factors of production are fixed and few are variable in short-run By changing variable factors ratio of factors utilized also changes and consequently quantity of production or output varies. This is called’ variable Proportion production Function’.

Normal Goods :- Normal goods are those goods for which the demand rises with every increase in the income of the consumer. In other words, in case of normal goods, there is a direct relationship between income of a consumer and his demand for normal goods, e.g. , the demand for rice and wheat will increase with every increase in income. Thus, rice and wheat are normal goods. 

Inferior Goods :- Inferior goods are low quality products and their demand decreases when the income of the consumer increases and vice versa. In other words, in case of inferior goods, there is an inverse relationship between demand and income of the consumer, e.g. , the demand for peanuts or bajra will fall with the rise in the Income of the consumer. Hence, peanuts and bajra become inferior goods at a higher level of income.

Value of Output

= Net value added at factor cost + Intermediate consumption + Depreciation + (GST – Subsidy)

= 100 + 75 + 10 + (20 – 5)
