Trichologist Answers Your Hair Questions

By Rebecca Anderson, Trichologist and Owner of Becky B Hair Salons, Queensland, Australia

Hair and scalp health is a complex topic that touches on genetics, lifestyle, and care routines. As a trichologist, my role is to bridge the gap between dermatology and cosmetology, offering science-backed solutions tailored to individual needs. Let’s dive into your most pressing questions about hair and scalp health.

What Is a Trichologist?

Trichology is the para-medical science of the hair and scalp, focusing on conditions like hair loss and related scalp disorders. The term originates from the Greek word “Trikhos”, meaning “hair,” and evolved as a specialised discipline in 1902. Trichologists use their expertise to assess and treat hair and scalp concerns, serving as a bridge between dermatological care and cosmetic solutions.

Common Hair and Scalp Concerns Answered by a Trichologist

What Causes Hair Loss, and How Can It Be Treated?

Causes of Hair Loss:

• Genetic Predisposition: Hereditary patterns like male and female pattern baldness.
• Hormonal Imbalances: Conditions like menopause or thyroid disorders will upset the level of your hormones.
• Stress: Chronic stress can trigger conditions like telogen effluvium.
• Nutritional Deficiencies: Low levels of vitamins or minerals like iron and B12.
• Damage: From heat styling, chemicals, or environmental factors.
• Hairstyles: Tight styles can cause traction alopecia.

Treatment Options:

Treatments range from topical solutions like minoxidil or aminexil to oral medications like finasteride for genetic thinning. Natural remedies and addressing deficiencies through supplements or dietary changes can also be effective.

Innovative treatments like B12 and biotin injections, platelet-rich plasma (PRP), and scalp needling can stimulate growth. Consulting a trichologist ensures the right solution is tailored to your specific needs.

How Can I Improve My Scalp Health?

A healthy scalp is essential for hair growth. Start by identifying your scalp condition:

• Dry and Flaking: May indicate dandruff or dryness.
• Sensitivity and Irritation: Could be linked to inflammation.
• Oily with Build-Up: Often caused by overactive sebaceous glands.
• Itchy or Unbalanced: May involve microbiome issues.

Tips for Scalp Care:

• Cleanse: Use a high-quality shampoo suited to your scalp type.
• Exfoliate: Incorporate a gentle scalp scrub to remove build-up.
• Moisturise: Hydrate with a targeted scalp serum.

Professional tools like the Kérastase K-Scan can analyse your scalp under a microscope to recommend specific treatments.

Why Is My Hair Thinning, and What Should I Do?

Causes of Hair Thinning:

Hair thinning often results from hormonal changes, genetics, stress, or poor nutrition. Shortened hair growth cycles, known as miniaturisation, can also play a role.

Hair Thinning Solutions:

• Diet Changes: Ensure a balanced intake of proteins, vitamins, and minerals.
• Scalp Treatments: Use serums or treatments designed to promote density.
• Seek Expert Help: A trichologist can assess your condition and recommend appropriate interventions.

How Often Should I Wash My Hair?

Wash your hair when it’s dirty, as sebum production varies between individuals. For conditions like seborrheic dermatitis, daily washing with a gentle, high-quality shampoo is crucial.

 

Are There Specific Diets for Healthy Hair?

A balanced diet is key. If avoiding meat, replace protein and vitamin B12 with plant-based alternatives. Supplements can help, but only if they address specific deficiencies.

Can Stress Affect My Hair?

Yes. High cortisol levels, triggered by stress, disrupt the hair growth cycle. Managing stress through lifestyle changes can significantly improve hair health.

When Should I See a Trichologist?

If hair loss exceeds the ordinary or if scalp issues persist despite home treatments, consult a trichologist. They use tools like microscopic scalp analysis, health histories, and blood test results to diagnose and treat effectively.

How Effective Are Hair Supplements?

Supplements work best when addressing specific deficiencies. A trichologist can guide you through the process, ensuring efficient and cost-effective solutions.

Hair Myths vs. Facts:

MYTH: Regular trims make hair grow faster.
Truth: Regular trims will keep your hair splits from travelling up the hair shaft. This will allow you to have long healthy hair but is only required when you have split ends.

MYTH: Changing shampoos frequently is necessary.
Truth: Build-up from silicones and harsh chemicals, not shampoo fatigue, often causes hair issues. Opt for sulphate- and silicone-free formulas for healthier results.

MYTH: Plucking a grey hair makes three more grow in its place.
Truth: A follicle can only produce one hair, plucking one grey hair will result in one grey hair growing in its place.

MYTH: Stress causes grey hair
Truth: It is not the only factor that can cause greying, stress can cause the release of norepinephrine, which affects melanocyte stem cells in hair follicles. This can cause the stem cells to turn into pigment cells or move out of the follicle. Without these stem cells, new hair grows in grey or white.

MYTH: Colour takes better on dirty hair.
Truth: Colour results are best on clean, dry hair that is free of product build-up.

MYTH: Wearing hats causes baldness.
Truth: Wearing tight hats for long periods can temporarily break hair or indent it, but it doesn’t cause permanent hair loss.

When in doubt, consult a trichologist to avoid self-treatment pitfalls.
