repigmentation in the treatment of alopecia areata and vitiligo, which may have a common
pathogenetic basis. Zhang & Wang (2023) proposed an innovative system for diagnosing scalp
disorders using deep neural networks, which allows for quick and efficient identification of
pathologies. Summarizing, the literature analysis shows a gradual movement from traditional
hygienic approaches to high-precision, personalized, and technology-oriented hair care methods.
The integration of dermatological, cosmetic, and bioengineering knowledge contributes to the
development of more effective products and techniques that can meet individual needs in the face
of growing environmental and human factors.
In this regard, a special role in the development of effective care programs is performed by
cosmetology specialists with modern knowledge of hair physiology, types of damage, as well as
the properties and mechanisms of action of care products. In particular, according to trichological
studies, only an individual approach to the choice of products and procedures based on the type
of scalp, hair structure and environmental factors can achieve a long-term positive result
(Abraham, 1990). A cosmetologist is obliged to be guided not only by the practical aspects of
care, but also by the composition of cosmetic products containing active ingredients such as
peptides, vitamins, antioxidants, phytocomplexes, and surfactants, which can have both positive
and negative effects if used unnecessarily (D’Souza & Rathi, 2015).
This research was based on the method of systematization and content analysis of scientific
literature, professional publications, clinical reviews, recommendations of the trichologists, as
well as information from open sources on the composition and mechanisms of effect of hair care
products. The main focus is on studies published in international scientific journals during the
past ten years to identify effective active ingredients, principles of care products selection
according to scalp type (dry, oily, sensitive, normal) and analysis of the impact of external factors
(environment, stress, frequency of shampooing, heat treatment). Moreover, a comparative
analysis of popular care products (shampoos, conditioners, masks, ampoules) on the professional
cosmetology market was conducted in terms of their composition, functional purpose and
accordance with scientific recommendations.
Results
Within the framework of modern cosmetology and trichology, the classification of head skin types
is of essential importance for the choice of hair care products and methods. Proper identifying of
the scalp type allows for individualizing the approach to the patient, reducing the risk of
dermatological complications, improving the condition of the hair, and achieving high efficiency
of preventive and therapeutic measures. According to dermatological sources, the scalp is
conventionally divided into five main types: normal, oily, dry, combined and sensitive (Lopez &
Garcia, 2024). A healthy scalp type is characterized by a balanced level of seboregulation and
absence of flaking, itching, or tightness. The hair looks healthy, has a natural shine, does not get
greasy excessively quickly, and the need for washing occurs every 2-3 days. This type of skin is
a typical skin type and is less common than others, especially in the adult population, as the
function of the sebaceous glands changes with age and under the influence of external and internal
factors (Cesarini, 1990).
Oily scalp is characterized by excessive sebum secretion, which causes rapid hair oily, especially
at the roots, shiny scalp, a tendency to follicle clogging, seborrheic crusting, and an increased risk
of developing oily dandruff. In such cases, inflammatory processes and microbiome disorders are
often observed, which requires thorough cleansing and the use of sebum-regulating products that
do not disturb the skin's hydro-lipid balance (D’Souza & Rathi, 2015). Dry scalp is manifested as
a lack of sebaceous gland activity, which leads to dehydration of the epidermis. Clinical signs
include flaking (sometimes mistaken for dry dandruff), tightness, itching, irritation, as well as
brittle and dull hair. Dry scalp often reacts to aggressive detergents and weather conditions, so it
requires delicate care with the use of moisturizing and lipid-regenerating components, including
ceramides, panthenol, and oils (Deeksha et al., 2014).
Combination scalp type combines signs of dry and oily skin as a rule, there is oily skin in the root
zone with simultaneous flaking or dryness in other areas, especially in the lower part of the hair
zone. This type requires gradual care that considers local needs: cleansing the scalp with a
tendency to oily and intensive nutrition of dry areas and hair length. The combined type is quite
