Tenderness of the scalp due to stress and the soothing effect of German chamomile hydrolate

Why does stress cause scalp tenderness?

Emotional stress activates the hypothalamic-pituitary-adrenal axis. This triggers a release of cortisol and corticotropin-releasing hormone (CRH), while the sympathetic nervous system releases norepinephrine and neuropeptides. These signals increase the production of proinflammatory cytokines. , which can lead to:

• Telogen effluvium – stress causes hair follicles to transition from the growth phase to the resting phase; massive shedding occurs 2–3 months after the stressful event .
• Excessive activity of the sebaceous glands – cortisol and androgens increase sebum production , which promotes the growth of fungi (Malassezia) causing dandruff and itching .
• Epidermal barrier disorders – cortisol and CRH impair keratinocytes and increase inflammation , making the skin more sensitive and tender.

Sensitive scalp is a form of skin hypersensitivity; its prevalence in the French population was 44.2%, and common triggers include pollution, high temperatures, emotional stress, and certain shampoos pmc.ncbi.nlm.nih.gov . It manifests as burning, stinging, tingling, or soreness pmc.ncbi.nlm.nih.gov . Experts also emphasize that stress and elevated cortisol affect the hair follicle; in the article, a trichologist is quoted as noting that stress causes oily or flaky skin because it disrupts the balance of the microbiome.

Benefits of Selected Essential Oils and Carrier Oils

• Almond oil (from sweet almonds) – soothes the scalp and intensely moisturizes it, and can help with dry and flaky skin. Massaging almond oil into your hair increases blood flow and infuses antioxidants, leaving hair soft and shiny (healthline.com webmd.com ).
• Cedarwood (Cedrus atlantica) oil stimulates the scalp and promotes hair growth. Traditionally applied to the scalp to stimulate hair follicles and hair growth. In one study, a mixture of thyme, rosemary, lavender, and cedarwood oils with jojoba and grapeseed oil improved hair regrowth in 44% of patients with alopecia areata, while the oil base alone worked in 15% (pmc.ncbi.nlm.nih.gov ). However, cedarwood oil itself has not been studied as a standalone preparation; scientific reviews rate the evidence for its effectiveness as limited (healthline.com ).
• Chamomile oil (Matricaria recutita or Chamaemelum nobile) – adds shine and softness to hair and soothes scalp irritations. Its high content of anti-inflammatory compounds (e.g., bisabolol, chamazulene) soothes irritated scalps. webmd.com faithinnature.co.uk . Antioxidants in chamomile neutralize free radicals and may promote a healthy scalp microbiota. faithinnature.co.uk .
• Clary sage oil (Salvia sclarea) – stimulates the scalp and promotes hair growth. In aromatherapy, it is used to stimulate hair growth and regulate sebaceous glands. webmd.com . It contains linalyl acetate, like lavender, but clinical evidence for its effects is preliminary.
• Coconut oil – a renowned emollient that softens hair, increases shine, and reduces protein loss. It can be used as a conditioner, mask , or serum; regular use helps prevent damage and keeps hair healthy and shiny.
• Geranium oil (Pelargonium graveolens) – strengthens hair and improves its condition. Sources attribute it to hair-strengthening and antibacterial properties, but available research on its effects on hair growth is limited. A literature review highlights that more research is needed to confirm these benefits. .
• Jojoba oil moisturizes hair, provides nutrients, and stimulates the scalp. A waxy plant substance similar to human sebum, it acts as an emollient that smooths the hair cuticle, reduces frizz and moisture loss, and soothes dry, tight scalps. apollo247.com
• Lavender oil – deeply nourishes hair, adds shine, and helps control dandruff. Known for its calming and antibacterial properties, a 2016 study showed that it stimulated hair growth and made hair thicker when applied to mice (healthline.com ). In 2025, a randomized, three-arm, double-blind trial with 90 participants was published comparing rosemary-lavender and rosemary-castor oils with coconut oil. After 90 days, rosemary-lavender oil significantly improved hair growth (approximately 58% increase), hair thickness and density, and reduced hair loss compared to coconut oil (P < 0.0001). pmc.ncbi.nlm.nih.gov A recent study from 2025 found that a rosemary-lavender preparation can stimulate hair growth, but this study examined the mixture, not lavender itself (pmc.ncbi.nlm.nih.gov ). Based on current data, lavender can be considered an adjunct ingredient with soothing and antibacterial properties, but its effect on hair growth in humans remains uncertain and requires further study. Lavender oil has antibacterial and antifungal properties that may prevent itching and dandruff (healthline.com ). A massage with diluted lavender oil not only soothes the scalp but, thanks to its aroma, helps reduce stress (healthline.com ).
• Argan oil (Moroccan) – intensely moisturizes, nourishes, and provides antioxidants. It contains unsaturated fatty acids, vitamin E, and antioxidants.

Research indicates that when applied to the scalp, it can increase microcirculation and stimulate hair follicles. In a small clinical study, rosemary oil was as effective as 2% minoxidil in improving hair growth and also caused less itching (health.clevelandclinic.org ). The compound carnosine present in rosemary has anti-inflammatory and antioxidant properties and improves blood flow to the scalp (health.clevelandclinic.org ).
• Sandalwood oil – helps condition dry ends and adds a pleasant fragrance to hair. Valued for its pleasant, woody scent, it is used in cosmetics to moisturize dry ends and as a natural hair fragrance (webmd.com ). Scientific evidence for its effect on hair growth is limited, but it adds softness and a subtle aroma to hair.

It works well as a toner for acne-prone skin and as a cool compress after sunbathing or shaving. The hydrolate is gentle, safe for children and pets, and has a 24-month shelf life. The hydrolate moisturizes, soothes redness, has anti-inflammatory properties, and can be used as a refreshing hair mist.
