What is cold air used for in a hair dryer?

Drying Rule #1: Gently wring out hair

The first thing you need to do is remove excess moisture from your hair. Because of it, the cuticle (the protective shell of the hair, consisting of transparent keratin scales) swells, which leads to increased fragility and increases the risk of split ends. Therefore, the shorter the contact with water, the better.

It is best to remove moisture with a soft, highly absorbent towel, such as microfiber. Do not rub your hair under any circumstances! This will have a detrimental effect on your hair. Vigorous rubbing damages the cuticle, softened by water, its scales literally stand on end. Because of this, the hair loses its smoothness and ability to reflect light, which means you can’t count on shine. The best way is to gently press a towel onto your hair and squeeze out the moisture. If you have long braids, you can twist them into a rope in a towel and then wring them out. It is enough if after this preliminary drying there is no water dripping from the hair.

Who needs to buy a hair dryer

A cold air hairdryer is necessary for frequent drying and styling of hair, especially hair extensions. If you have problems with split ends, cold air will also help prevent them. If you want to protect your hair from harm, this is definitely your option.

Trichologists advise buying a hair dryer with a cold blow function for those who have already suffered from problem hair. The effect is not noticeable immediately; it takes several weeks to see results.

Drying rule No. 3: do not neglect thermal protection.

It doesn't completely protect your hair or reduce hair dryer damage, but it helps. In general, thermal protection works like this: a product with special components coats the hair and redistributes heat. In addition to thermal protection, hair oil will also play a good role. Apply it to damp hair, let it absorb a little and proceed to dry your hair. Hot air activates protective substances, and you will achieve perfect styling without harm to your hair!

Drying rule #5: Don't overdry your hair.

When drying with a hairdryer, you need to “keep a distance” - about 20 cm and constantly monitor the temperature. Plus, you can purchase a hair dryer with an ionic effect. To keep your hair smooth and shiny, direct the air from top to bottom. This is how you smooth out the scales. Stylists also recommend leaving your hair slightly under-dried to avoid evaporation of all moisture from the hair structure and destruction of the protective shell. At the end of drying, it is best to switch the hair dryer to cold blowing mode: this will smooth out the cuticle scales, add shine and help quickly “cool” the hair.

Hair dryer for volume

Using a hairdryer can only add volume to well-washed hair. For washing, it is advisable to use shampoo and conditioner designed to increase the volume of hair.

To give your hair volume, tilt your head down while drying.

To add root volume, proceed as follows:

1. Place a turban-shaped towel on your head and let it absorb the water before drying.
2. Apply heat protection and hold products along the entire length of your hair.
3. Dry your hair with a hairdryer, but not completely.
4. Divide your hair into sections (crown, nape and temples), secure the strands with hairpins.
5. Start drying from the back of the head, then move to the temples, and finally dry the top of the head (with your head down). During drying, break each zone into small strands and blow air in turn.
6. Lift each strand perpendicular to the surface of the skin at the roots using a round comb.
7. Dry your curls by directing the flow of warm air from roots to ends, and not vice versa.
8. After drying the strands, blow it with cold air.
9. Do not rush to comb your hair after drying, wait until it cools completely.
10. Apply varnish to the root zone to fix the volume if necessary.

Heat protection spray provides additional hold. To create additional volume, use a heat-protective mousse: apply it to your hair at the roots.

You can achieve maximum volume when drying with a hairdryer by performing all manipulations when your head is lowered.

Drying Rule #6: Use attachments.

There are 2 types of hair dryer attachments: concentrators and diffusers. What are concentrator attachments? The concentrator is a flattened cylinder that fits onto the nozzle of a hair dryer. The air comes out of this nozzle differently - in a narrow and strong stream, which reaches maximum pressure precisely at the strand to which it is directed. And it intensively warms up this strand. The hair dryer itself has a relatively wide socket, from which hot air comes out at high speed ─ in a wide and voluminous stream, freely diverging throughout the space.

What is the concentrator attachment for? This nozzle itself speaks about its function by its name. The nozzle concentrates air on a specific strand, thereby preventing other strands from overheating.

What are the dangers of using a concentrator? The air stream from the hairdryer should not be directed at the skin at all. Faces and ears are clear to everyone. But more than that, it should not be directed to the scalp. Dry so that only your hair is exposed to the stream. Otherwise - dry skin, dandruff or even small burns. So, when using a concentrator you need to be as careful as possible in this regard. When it comes to hair, when using a concentrator you need to work quickly and time your work with the strand well. Don't overdo it and don't fall asleep with your eyes open while working with a hairdryer. If the strand is already ready, cool it and move on. In addition, remember - the distance between the nozzle of the concentrator and the strand should never be less than 2-3 centimeters.

What are diffuser nozzles? Unlike concentrator nozzles, diffuser nozzles work in the opposite way - they break the air stream into several weaker ones, due to which the hair suffers much less. The diffuser, unlike the concentrator attachments, is attached to the hair dryer with a narrow part. At the base of the teeth there are holes through which air enters. It is this design feature that helps reduce the negative impact of high temperatures on the health of the hair and scalp.

What is a diffuser nozzle used for? Diffuser attachments create that natural effect of root volume and light curls.

Which diffuser should I use? The Termix diffuser is a universal tool that is suitable for any hair length and thickness. Due to the specially selected distance between the teeth, long hair will not get tangled, and short hair will be completely captured. High quality plastic will not melt, allowing you to use the diffuser every day. Made of silicone tube, the Termix diffuser will not slip or fall off your hair dryer, which usually happens with concentrate attachments. And also two superimposed filters with a rotating base allow you to adjust the required volume of hair and create additional comfort during styling.

Drying and styling hair using cold air

The fact that constant exposure to high temperatures on hair only has a negative effect is known to everyone. But at the same time, few people can refuse to use a hair dryer, since only in this case can they give their hair the necessary shape, make it more voluminous, straighten or, conversely, curl the strands. Of course, curly curls can be created with other devices, such as curling irons, and curls can be straightened with an iron. But the fact that in this case the strands will not just be blown with a hot stream, but the metal surface of the device, heated to a significant temperature, will directly touch them, makes such processes even more harmful. Therefore, using a hair dryer or hair dryer brush is one of the safest methods of exposure, and when asked why it is needed in a hair dryer, the answer immediately becomes clear and understandable.

But, nevertheless, elevated temperature, especially if its effect is used constantly, dries out the curls, depriving them of the amount of moisture necessary for a normal appearance. At the same time, the hairs begin to break and fall off, and the hairstyle takes on an unkempt appearance. It is precisely so that a woman has the opportunity to prevent this, and at the same time use a hairdryer, and the possibility of using lower temperatures was created. Using cold air increases the required exposure time until complete drying, but the negative impact on the hair is minimized.

Negative effects of hot drying hair

In addition to drying curls at a low temperature, answering the question of why cold air is needed, you can answer that it is to fix the hairstyle. So, for example, when using a round brush in a hair dryer to create curls, at the very last moment you need to turn on cold air, thereby securing the curled curl. This will prevent the strands from losing their shape. In this case, varnish is used as a last resort to ensure that the hairstyle remains beautiful for a longer time.

Drying Rule #8: Use the right styling tools.

Drying rule No. 9: do not forget about cold airflow.

Cold blowing closes the hair scales and fixes the hairstyle. A strand of hair, curled and styled as needed under a hot air dryer, is suddenly blown with cold air. 4-5 seconds of blowing - and that’s it, you can move on to the next one, this one is fixed. Why is this happening? The fact is that the elasticity of hair depends greatly on its temperature. Hot hair changes shape more easily. Then we reason logically - a heated strand, laid in the shape you need, remains heated. And while you start working with the next strand, this one begins to lose the shape it was given. Cooling stops this process and fixes the hair exactly in the position in which it is currently located. And then it keeps this shape well. By the way, the cold blow button on professional hair dryers is located so that it can be pressed briefly without being distracted by the switch that turns off the heating.

For styling

Why do stylists use cold air? In order for the styling result to last longer. Here are some tricks they use.

You can style your hair with hot air, but using a hairdryer with a cold blow function is easier and more reliable. If you use only cold air, then nothing will work; first there is hot and then cold drying.

How to do the styling correctly:

• Apply foam to your hair, wrap it around a round comb;
• Fix the foam with hot air;
• Switch the hairdryer to the cold blow function for 4-5 seconds
• Secure the resulting strand with hairspray.

If you want to style your hair extensions, do not bring hot air close to the glue capsules, otherwise it will begin to dry out. Curls can be curled on damp hair using curlers: blow cold air over the roots, or hot air along the outer contour.

It works simply:

• The foam heats up and cools sharply, fixing the strand.
• Without intentional blowing, the foam cools down slowly, and during this time it has time to “drain”, unraveling the curl.

If you do not use foam, then the mechanism is as follows:

• Elastic hair is easily deformed at high temperatures.
• As it cools slowly, it better acquires its original shape, and this happens when you warm up one strand, release it and move on to the next one. Cold drying fixes the strand in the position that you gave it with hot drying.
