It all depends on the level of their initial quality (the number of follicles on the head and the condition of the cuticle, and this is a genetic condition) and the degree of accumulated damage over a certain period of time. Those. It is much easier and easier to grow hair that is natural and not spoiled by long-term dyeing and thermal damage, for example, after an unsuccessful short haircut, than trying to restore those that have undergone long-term chemical or mechanical damage to a state of child's intactness.
In the first case, folk methods and means work well, you should not invent a bicycle and buy expensive drugs or go to, in fact, unnecessary procedures. The main thing is to maintain the proper level of nutrition and hydration of both roots and ends, not to overdo it with irritating factors that stimulate the scalp (pepper, ginger, mustard and other "intoxicating" masks), otherwise for relatively healthy hair and skin this can bring a negative effect (the same (most concerns overly nutritious care).
In the second case, you need to take care of the internal state of the body, nourish from the inside with special vitamins and additives designed to restore the skin - unsaturated vegetable fats, B vitamins, a sufficient level of protein intake in the diet. For a better selection of the vitamins and minerals themselves, it is better to first undergo a biochemical blood test for trace element composition, but the general recommendations remain in the same format: more good fats, adequate protein intake, reduction of simple carbohydrates and physical activity (oxygen saturation).
It is rarely possible to restore the number of follicles that was initially before the executions (if not to say that it is not possible at all), but improving the microcirculation of blood to those follicles that remain is the most effective influence to restore the satisfactory state of any skin, and the head, in particular, too. In case of success and improvement of not only the visual state, but also the objective self-awareness of hair health, you can also practice some wellness procedures in specialized salons: scalp mesotherapy, darsonval treatment, etc. Well, take care, take care and take care of it again, choose light organic shampoos, do not forget about balms and masks, do not succumb to the temptation to stupid and fashionable experiments so that later not to resurrect from the ashes what could be cared for and cherished, giving beauty to yourself and others :)
Hello. About oils is a controversial point, the myth about their benefits has long been dispelled, it is better to apply them only on the hair itself, and not on the roots, because. oils clog the hair follicle and they grow poorly, the opposite effect. In addition to all the listed funds, I will also name the fact that it is recommended to wash your hair with your head down, so blood circulation improves. Yes, and during the day, tipping your head forward several times, it is useful to change position for hair growth. I hope you found something useful.
Firstly, it is better to contact a trichologist.
Secondly, unfortunately, it will not work quickly, here you need a whole range of care products and a general understanding of how to generally handle hair and scalp. The density and health of your hair depends on nutrition, lifestyle, and how, with what and how often you wash your hair, even how you wipe, dry, comb, you will be surprised, but even on what pillowcase, sleep. Also on your age, genotype, morale (how often does stress visit?)
In principle, regardless of all this, you can "wake up" sleeping phallicules and accelerate the growth of existing hair with the help of oils (castor, burdock , linseed, cold-pressed olive (yes, even food is suitable), scalp massage, proper combing, intake of vitamins A, B and E, masks with a warming effect (mustard, pepper), and yes, as already mentioned, you have to be careful with this.
Plus there are whole lines of tools that really work (trichlog will be the best choice).
Unfortunately, for the most part, it all depends on the structure of the hairline, and not always a product that increases hair volume by 3 or 4 times is right for you. However, despite this, there are many professional and natural masks. It is difficult to advise anything from professional cosmetics, because everything is very individual. But if we consider the means so that there is benefit and the prices do not bite, then I can recommend the INDOLA line. Hair really does not weigh down and smells delicious.
Of natural means, burdock and castor oil promotes hair growth. It is necessary to apply to hair for half an hour - an hour, then rinse thoroughly. And do this 2 times a week. I've heard a lot of positive reviews from these oils. Also, mustard powder occupies the 2nd place in the ranking of natural remedies. He allegedly heats the bulbs, which stimulates hair growth. But be prepared that it really warms up, so you won't go through more than half an hour with such a mask.
