How to Handle Sensitive Scalps and Allergies During Treatment

Expert Guidelines for Safe and Comfortable Keratin Services

Introduction: Smooth Hair Should Never Come with Discomfort

As demand grows for professional keratin hair treatments, so do concerns about sensitive scalps, allergies, and client safety. Even with high-quality formulas like Brasil Cacau, which are formaldehyde-free and enriched with nourishing ingredients, individual sensitivities still exist.

For professional stylists, the ability to handle sensitive clients with care—and confidence—is essential. This guide outlines how to assess, adapt, and deliver keratin smoothing treatments without compromising comfort, results, or client trust.

1. Start with the Most Important Step: Consultation

Before offering any keratin treatment, ask the right questions. A thorough consultation will help you identify red flags early and adapt your protocol.

Ask your client:

  • Have you had a keratin treatment before?

  • Do you have any known allergies to hair products, fragrances, or cosmetic ingredients?

  • Do you often experience scalp irritation, flaking, or itching?

  • Have you had any recent dermatological treatments on the scalp?

Pro Tip:
Keep a digital or paper form as part of your intake to document responses. This protects both the client and your business.

2. Understand the Difference Between Reaction Types

Allergic Reaction

Triggered by immune response. Can involve swelling, burning, rash, or respiratory symptoms.
→ Even the gentlest product must be avoided.

Sensitivity/Irritation

Usually localized discomfort from fragrances, heat, or incorrect application.
→ Can often be prevented or minimized with precautions.

Brasil Cacau’s formula is designed for salon safety, but identifying which category a client falls into will shape your next move.

3. Perform a Patch Test When in Doubt

If a client reports any history of product reaction or sensitive skin, always conduct a patch test 48 hours before the treatment.

How to do it:

  1. Apply a small amount of product (Anti-Residue Shampoo or Thermal Reconstruction) behind the ear or on the inner arm.

  2. Leave it for 15–30 minutes, rinse, and observe for 24–48 hours.

  3. If there’s any redness, itching, or discomfort — do not proceed with full treatment.

Patch testing builds client trust and minimizes risk.

4. Use Protective Application Techniques

Even with a safe formula like Brasil Cacau’s Thermal Reconstruction, proper technique makes all the difference for sensitive clients.

Use these precautions:

  • Do not apply directly to the scalp. Keep product 0.5–1 cm away from roots.

  • Use a fine-tooth comb to evenly distribute and avoid buildup near the scalp.

  • Ensure full product removal before flat ironing or sealing.

  • Keep the salon well-ventilated, especially during heat application.

Remember: discomfort often comes from improper technique, not product.

5. Choose the Right Heat Level

Sensitive scalps may also respond poorly to excessive heat. While heat is essential to activate the keratin, it must be adjusted for client comfort.

General Guidelines:

  • For fragile, processed, or irritated scalps: use 180–200°C (356–392°F)

  • Avoid contact between flat iron plates and scalp

  • Use longer passes at lower heat, rather than high-temp quick passes

With Brasil Cacau, heat efficiency is high—so results won’t suffer from gentler application.

6. Post-Treatment Care for Sensitive Clients

Help clients maintain comfort and results with aftercare tailored for sensitive skin.

Recommend:

  • Sulfate- and salt-free shampoo (Brasil Cacau Home Care range)

  • Avoiding heat styling for a few days post-treatment

  • Gentle brushing and scalp massage to stimulate circulation

  • Using silk pillowcases and avoiding tight hairstyles

Offer clear written aftercare instructions and follow up after the service to check in.

7. Know When to Say No

As a professional, it’s your responsibility to put client safety first. If:

  • The patch test is reactive

  • The scalp is visibly inflamed

  • The client is pregnant or under medical treatment for skin/scalp conditions
    → kindly advise against treatment and suggest alternatives or a later date.

Brasil Cacau prioritizes hair health—but your expertise ensures the full client experience remains safe and comfortable.

Conclusion: Safety Is the New Luxury

Modern clients care about results—but they care even more about how they feel during and after the service. When you combine the salon-grade power of Brasil Cacau keratin treatment with sensitivity-aware practices, you set yourself apart as a true expert.

Because the best smoothing experience is not just effective—it's also gentle.
