## 🎯 Key Points

- Hair health depends on the condition of the scalp, not just the shampoo.
- It is recommended to wash the head twice, leaving the shampoo on for 2-3 minutes.
- Deep cleansing with a peel or scrub should be done once every 7-10 days.
- Annual testing for thyroid hormones and ferritin is mandatory.
- Using a silk pillowcase and drying on a cool setting prevents breakage.

In a world where the beauty industry offers an endless array of serums and masks, experts increasingly remind us of fundamental truths. Healthy hair is not the result of using a dozen jars, but the consequence of a systematic approach to the health of the scalp and the body as a whole. In August 2026, trichologist Yuliya Yerstenyuk, sharing her personal routine with the Wave RBC.UA publication, outlined principles that have become a gold standard for many patients.

### Fundamental Principle: Cleansing and Stimulation

According to the expert, hair care cannot be reduced to just choosing a shampoo. The key mistake made by most is ignoring the condition of the scalp. Yerstenyuk emphasizes that care is based on two pillars: quality cleansing and stimulation. She turns the process of washing hair into a therapeutic procedure: shampoo is applied twice, with mandatory scalp massage and leaving the product on for 2–3 minutes. This approach allows for the effective removal of sebum, styling residue, and pollutants that often block oxygen access to the follicles.

### Deep Cleansing and Active Ingredients

Standard washing is not enough to maintain scalp health. The trichologist recommends performing a deep cleanse with a trichological peel or scrub once every 7–10 days. This procedure removes dead skin cells, preparing the skin to absorb active ingredients. After washing, a scalp serum containing peptides and plant extracts is often used. However, the doctor warns against blindly following advertising: products with active ingredients must be selected strictly according to the individual needs of the skin and the current condition of the hair.

### Temperature Regime and Sleep Textiles

Mechanical and thermal impact on hair plays a critical role in its preservation. Yuliya Yerstenyuk adheres to the rule of washing her head with warm, not hot water, to avoid provoking excessive activity of the sebaceous glands. Hair drying is done with a hairdryer on a medium or cool setting. The sleep regime deserves special attention: the doctor categorically does not go to bed with wet hair and uses a silk pillowcase instead of cotton. Silk reduces friction, preventing breakage and split ends, which is especially important for long hair.

### Medical Control and Laboratory Indicators

Cosmetic care does not replace medical observation. The trichologist annually checks key health indicators: thyroid hormones, ferritin levels, and total protein. These parameters directly affect hair growth and structure. If active hair loss or changes in the condition of the scalp are observed, cosmetic products may be insufficient, and the intervention of a trichologist or dermatologist is required to identify internal causes of the problems.

### Contradictory Data

Although the trichologist's recommendations seem logical, there are disagreements within the expert community regarding the frequency of peel use. Some dermatologists believe that for sensitive scalps, using scrubs once every 7 days may be excessively aggressive and provoke microtraumas. At the same time, proponents of aggressive cleansing insist on the necessity of frequent removal of the stratum corneum for better penetration of serums. In this case, the choice of procedure frequency should be based on the individual reaction of the skin, rather than universal recommendations.
