With the advancement of age ,hair of males starts thinning due to

Options

A. Falling of hair
B. Low ATP formation
C. Reduced rate of protien synthesis
D. None of above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why males experience hair thinning as they age. This involves understanding the biological processes related to hair growth and the factors that influence it.

2. **Identifying Key Proteins**: Hair growth is primarily dependent on proteins, particularly keratin. Keratin is a fibrous protein that forms the structure of hair.

3. **Role of Biotin**: Biotin, a B-vitamin, plays a crucial role in the synthesis of keratin. It is essential for healthy hair growth. However, the question focuses on the factors affecting hair thinning rather than the growth itself.

4. **Evaluating the Options**:
- **Option 1: Falling of hairs** - This is a result of hair thinning, not a cause.
- **Option 2: Low ATP formation** - ATP (adenosine triphosphate) is energy currency in cells, but its low levels do not directly affect hair growth.
- **Option 3: Reduced rate of protein synthesis** - This option is significant because if protein synthesis decreases, the production of keratin will also decline, leading to hair thinning.
- **Option 4: None of the above** - This option can be dismissed since we have identified a valid cause.

5. **Conclusion**: The correct answer is that hair thinning in males with age is primarily due to a reduced rate of protein synthesis, which affects keratin production.

**Final Answer**: The hair of males starts thinning due to a reduced rate of protein synthesis.
