We learn how to dry our hair properly, following the instructions from the Cambridge academician.
Did you know that drying your hair naturally is much more dangerous than using a hair dryer? And the fact that going to bed with a wet head means shortening the path to split ends to a minimum? Cambridge University scientist, trichologist Tim Moore has been researching the process of drying hair for several years and, in the end, wrote detailed instructions on how to do it correctly.
Why is it harmful to dry your hair without a hair dryer?
Dr. Moore says that “natural drying” is the worst thing you can do with your hair. He explains it like this. The contact of hair with water from the first seconds at the molecular level changes their structure, by the way, not the simplest. Each hair is a complex structure. First of all, it has an external protective layer (cuticle) consisting of several layers of keratinized cells of elongated shape, the so-called hair scales.
The main part of the hair is the cortex, formed from pure protein, carotene. It is responsible for the volume of the hair (determined genetically) and its color (chemical processes of pigment change occur in the cortex). The central element of the hair (however, not everyone — for example, it is not in the downy hairs) – medulla, the brain substance responsible for thermal conductivity (our strands heat up or cool down depending on the temperature of the medulla).
What happens when we wash our hair or just wet our hair? Try to imagine yourself inside a house with a leaky roof: when it comes to hair, the cortex will be in your role, and the cuticle will be a tile through the gaps in which moisture penetrates inside. Because of the water, the cortex swells, and the hair increases in volume. It would be nice if he did not become very fragile and practically defenseless, because the scales of the cuticle, softened, fully open.
Most importantly, the longer we leave the hair wet and the longer the contact with water lasts, the more they continue to swell, “stretching” the poor cuticle. At the same time, each wash followed by slow drying repeatedly tests the protective layer of the hair, causing cracks to appear on the protective layer. Take pity on your hair, Tim Moore convinces: dry it immediately after washing.
The second terrible mistake that he advises to avoid is going to bed with wet hair. Yes, in order to save time, we often go to bed as soon as we have washed our hair. By doing so, you can cause damage to the hair, the correction of which will take many months. What’s the matter here? In a dream, we make involuntary movements, including crawling our head on the pillow too — this friction is quite strong and can lead to thinning and brittle hair (in general, this is about the same as if you left the house with wet hair, pulling a hat on them).
By the way, weather conditions greatly affect the quality of drying: high humidity will instantly reduce all styling efforts to zero — use a heat-protective spray to reduce its impact on the hair. Tests conducted by Dr. Moore showed that, no matter how hard it is to believe, our hair feels best in winter — on a cold, clear day at a temperature of zero degrees.
As for the means of care, the doctor is surprisingly loyal, advising to focus on the average price category. He assures that both luxury products and mass market have been tested in laboratory and field conditions. It turns out that “luxury expensive bottles” are not worth paying an exorbitant price for them. As soon as you spend more than £30 on a product, the results reach a plateau (we don’t quite agree with this, because the price of more than two thousand rubles should at least work on the placebo effect). Of course, super-cheap products won’t make your hair great either. Summary: choose the “golden mean” – leaving the brand of the middle category (however, it’s still up to you to decide).
So, backed up by knowledge, we go to dry our hair in a new way – correctly and without harm:
In conditions of constant time pressure, when we barely have time to wash our hair, we try to quickly pick up a hair dryer. Slow down, Dr. Moore advises. First you need to gently dry your hair with a towel: wrap it around your head, capturing the length of the hair, and massage it easily to absorb the main excess moisture.
Combing wet hair is not recommended, but you need to prepare for drying. In no case do it with a brush or brushing! Take only a comb or comb with large sparse teeth in your hands and slowly move from the tips to the roots (exactly in this — reverse – direction). If the hair continues to get very confused, try the following: for a few minutes, walk over it with a cold air jet and “layer” with your fingers.
Using thermal appliances to work with wet hair can have disastrous consequences for them. Imagine what happens to water at the highest possible temperatures: it turns into steam, which expands. Drops of moisture remaining inside the hair, when heated, can literally flare up, practically incinerating its contents. There is only one advice here: use thermal protection sprays after drying and before laying and avoid temperatures above 210 degrees — this greatly harms both their color and quality.
