Names of ampoules for hair loss, top products with amineksilom
We will not just list the names of ampoules from hair loss, the top - that is, the very top ones in their numerous lists, but we will try to bring the full composition of the fluids contained in them and the principle of operation of individual substances. It is unlikely that this will be a rating, but information about the components will help make a choice in favor of the most effective means.
What contain ampoules from hair loss and for hair growth?
Let's start with aminexil (2,4 diaminopyrimidine oxide), which contain as the main active ingredient:
- Derkos ampoules - Dercos Aminexil Pro and Dercos Aminexil Clinical - by Vichy French company (Vichy Laboratories);
- ampoules for hair loss Loreal amineksil - Aminexil Advanced L`Oreal laboratories:
- Kerastaz (Kerastase Specifique Aminexil Force R) - ampoules of hair loss for men and women (trademark L `Oreal);
- Ampoules Revivexil (Anti-Hair Loss Treatment Concentrate), Revlon Anti-Hair Loss, Indian Ampoules Matrix (MATRIX Biolage ScalpSYNC), etc.
Aminexyl, which has an international patent, but still not approved by the FDA (USA), is a vasodilator that activates blood circulation in the hair follicles and thereby restores their viability, preventing excessive formation of collagen around them (perifollicular fibrosis). However, amineksil can cause side effects in the form of hyperemia, peeling and itching of the skin in areas of application, similar to allergic dermatitis. 
Also in the Dercos (Vichy) ampoules there are: patented SP94 molecules (which penetrate the hair roots and transform into ceramides - the main hair lipoproteins);  the amino acid arginine (through the stimulation of the potassium channels of the cells dilates the skin vessels, contributing to better trophism of tissues) Vitamins for hair follicles that enhance nutrition of hair follicles from falling out in ampoules Vichy (Dercos Aminexil Pro) are represented by niacin (vitamin B3) and pyridoxine (vitamin B6).
If pyridoxine helps prevent the formation of dandruff, then nicotinic acid in ampoules from hair loss (synonyms - niacin, vitamin B3, PP, nicotinamide, niacinamide) - dilates blood vessels, that is, allows you to “feed” hair follicles.  In addition, as trichologists suggest, niacin reduces cholesterol accumulation in scalp sebocytes, which is transformed into the 5α-reductase enzyme, directly associated with an increase in dihydrotestosterone (DHT) and hair loss in men and women.

In addition to aminexil, Loreal Aminexil - Aminexil Advanced L`Oreal ampoules for hair loss - have a complex of amino acids - copper-tripeptide-1, similar to the GHK-Cu complex contained in biological fluids of the body. This complex helps stimulate hair growth by blocking the conversion of testosterone to DHT. 
Kerastase Specifique Aminexil Force R ampoules have two more important ingredients. First, it is rhamnose - natural deoxysacchar, a stimulating vascular endothelium growth factor (VEGF), which, in turn, increases the vascularization of hair follicles and increases their nutrition. 
Secondly, it contains the phytosterols madeacasinic (Asian) acid known from Ayurveda Centella Asiatica (Centella asiatica) - plants with antioxidant and lipolytic properties.
Instead of aminexil, a new patented substance stemoxydine (stemoxydine), which awakens dormant stem cells CD34 + near the skin surface, is introduced into the Vichy Dercos Neogenic ampoules and Kerastase Densifique ampoules (L'Oreal), which leads to an increase in the number and density of hair follicles. 
Ampoules with placenta for hair loss
Placent Formula (Italy), Placentrix (Farmagan, Italy) placental hair loss ampoules, Dikson Polipant ampoules (Dikson), and their analogues - Placenta Silhouette Plus Revitalizer (Schwarzkopf, Henkel Group, Germany), Placenta PLACO (UK) and others - contain biostimulating extract of animal placenta proteins (including amino acids, hormones and growth factors). 
Nutrition and oxygenation of the hair follicles can be improved due to the formation of additional capillaries in the skin and subsequent blood flow. But the result will be visible if these funds are applied daily and for a long time.
Therefore, experts warn that their use during pregnancy is contraindicated - because of the risk of developing tumors of the uterus or mammary gland, and use for children is unacceptable, since the hormones they contain can cause premature sexual development.
Placentrix classic intensive lotion (Farmagan, Italy) complements the action of the placenta with niacin, tocopherol (vitamin E, which normalizes blood circulation and strengthens the hair roots),  stimulating plant extracts, and zinc, which is a cofactor of many enzymes that provide biochemical processes in the dermis and hair follicles.
Ampoules Dikson Polipant (Dixon) also contain emulsion of castor oil and wheat germ; nettle and red pepper extracts; niacin, pyridoxine, pantothenic acid (vitamin B5), inositol (vitamin B8).
Ampoules of hair loss, containing a dwarf palm extract
Fruits growing in the southeastern United States of dwarf palm serenoa (Serenoa repens), according to another classification called Sabal serrulata, have phytosterols - campesterol, stigmasterol, β-sitosterol, which reduce sebum production and 5α-reductase activity (see previous section), that is, are natural anti-androgens. They are also rich in unsaturated fatty acids. 
The fruit extract of this palm is part of the concentrate of Italian ampoules from hair loss Rinfoltil (Rinfoltil), BioKap (Naturalforme, France), Phytolium 4 Concentrate (Phyto, France), and also contains ampoules from hair loss for men Kemon Actyva P Factor System Uomo ( Italy).

The prevalence of androgenic alopecia in men is 67.1%, in women - 23.9%. The prevalence and severity of androgenetic alopecia correlates with age in both sexes.  Up to 13% of premenopausal women have some signs of androgenic alopecia. However, the frequency of androgenic alopecia in women after menopause increases significantly, and, according to one author, it can affect 75% of women over 65 years of age.  Among Italians, the prevalence of androgenetic alopecia is estimated by experts at the level of 12.4% of the total population (higher in 12.8% only in Germany); for comparison in other countries: USA - 11.8%; Great Britain and Sweden - 11.7% each; Canada - 11.5%; Spain - 11%; Australia –10.3%.
