Assessment Guidance
Guidance for achieving higher grades
- 💡Always link health and safety points to specific salon procedures and legal requirements.
- 💡Use technical terminology correctly, such as 'disulfide bonds', 'alkaline', and 'pH'.
- 💡When answering questions about factors, consider client's hair type, condition, desired result, and any contraindications.
- 💡In practical assessments, demonstrate a methodical approach: consultation, patch test, protection, application, timing, neutralization, and aftercare.
- 💡Always follow manufacturer instructions for timing.
- 💡Use protective gloves and adequate ventilation.
- 💡Document client history and patch test results.
- 💡Always document every step of the consultation, even if it seems repetitive, to demonstrate thoroughness.
- 💡Memorise the active ingredients in relaxers (e.g., sodium hydroxide, guanidine hydroxide) and their effects on hair bonds.
- 💡Practise timing for different hair textures and use a timer prominently during assessment to show control.
- 💡Verbalise your health and safety checks as you perform them so the assessor notes your awareness.
- 💡Provide photographic evidence of your step-by-step process, including pre-treatment hair analysis and post-treatment results.
- 💡Include a detailed risk assessment for chemical use and your salon's emergency procedures in your assignment portfolio.
- 💡Demonstrate understanding of the science by explaining the action of relaxers on disulfide bonds and the role of neutralizers.
- 💡Use a clear, consistent labelling system for your written work to reference the specific health and safety regulations adhered to.
- 💡Always document your consultation thoroughly, including client expectations, hair analysis, and any allergies. This shows you understand the importance of client care and legal requirements.
- 💡Practice your timing during assessments. Many students run out of time because they spend too long on one section. Use a stopwatch during practice to pace yourself.
- 💡For colouring, always perform a strand test and patch test 48 hours before the service. This demonstrates professionalism and adherence to safety protocols, which examiners look for.
Common Mistakes
Common errors to avoid in your coursework
- Failing to carry out a patch test or skin test before the relaxing service, leading to potential allergic reactions.
- Applying relaxer to the scalp without a protective base, causing chemical burns.
- Leaving the relaxer on for too long, resulting in over-processing and hair damage.
- Not considering the client's hair history, such as previous chemical treatments, which can affect the outcome.
- Overprocessing hair leading to damage.
- Not performing a strand test before application.
- Ignoring scalp conditions or allergies.
- Skipping the strand test, leading to unexpected hair reaction or damage
- Over-processing the hair by exceeding the recommended development time
- Failing to fully rinse out the relaxer before neutralising, causing residual chemical damage
- Applying relaxer to previously relaxed hair without recognising the risk of breakage
- Neglecting to check the client's scalp for abrasions or irritations prior to service
- Under-processing or over-processing due to incorrect timing or product strength selection, leading to ineffective straightening or damage.
- Failure to perform a strand test prior to full application, resulting in unexpected adverse reactions or breakage.
- Overlapping chemical application onto previously relaxed hair, causing severe weakening and breakage along the demarcation line.
- Inadequate neutralization leaving the hair alkaline, which continues to process and compromises long-term hair integrity.
- Misconception: You can skip health and safety if you're careful. Correction: Health and safety is a legal requirement and a core unit; failing to follow procedures can lead to accidents, infections, or disqualification.
- Misconception: Cutting hair is just about following a pattern. Correction: Each client's hair texture, growth patterns, and face shape require adaptation; a good cut involves consultation and visual assessment.
- Misconception: More developer means lighter colour. Correction: Developer strength (volume) affects how much the hair lightens, but it also damages hair; using too high a volume can cause breakage and uneven results.
