hair problems that becomes irreparable

Yes, that is completely true hair damage is caused due to this and I most dont use hair dyers...

Hair dryers are the most frequently used hair styling tools, but improper use can result in severe heat damage and dull, lifeless hair. To use a dryer effectively, choose the model that best suits your needs and try to limit the amount of heat you apply. Adding heat treatment products and conditioners can help moderate damage, and careful use can result in superior hair styles that never look like a dryer has been used at all.

Blow dryers, flat irons, and similar devices. Frequent use of a blow dryer tends to damage hair. The high heat from a blow dryer can boil the water in the hair shaft leaving the hair brittle and prone to breakage. Allowing the hair to air dry and styling it only when dry will lessen this risk. Dermatologists also recommend limiting the use of flat irons, which straighten hair by using high heat, and other devices such as curling irons.

Blow dry your hair as little as possible.

The heat from a blow dryer can aggravate dry, damaged hair and contribute to formation of split ends. Heat causes expansion of the hair shaft followed by contraction with cooling. This places a lot of excess stress on the hair, resulting in breakage. Let you hair dry naturally and save the blow dryer for days when you're in a real pinch for time and, then, only use it on a low setting.

Blow-Drying Bad for Hair?
Answer: Yes. Overdrying the hair causes strands to dry out and break. Your best bet is to blowdry your hair 80 percent dry, and let the rest dry naturally OR do the exact opposite: Let hair naturally dry half-way, then finish with the blowdry. When you can, I recommend skipping the blowdryer altogether.
