Common Mistakes
Common errors to avoid in your coursework
- Failing to conduct a skin test or patch test 48 hours before the colouring service, risking allergic reactions and legal liability.
- Overlapping colour on previously coloured hair, leading to uneven results, banding, or over-processing, and not considering the natural undertones during colour selection.
- Failing to perform a preliminary strand test on pre-coloured or sensitised hair, leading to unexpected results or damage.
- Applying colour directly to the scalp without considering the natural underlying pigment, resulting in banding or an unnatural tone.
- Overlapping or incorrect saturation, causing patchiness or an uneven colour outcome, especially with regrowth applications.
- Underestimating the importance of client protection (e.g., skin staining, gowning) and insufficient ventilation, compromising safety and comfort.
- Failing to perform a patch test prior to colouring, leading to allergic reactions
- Not assessing hair porosity, leading to uneven colour results
- Incorrect product mixing ratios, causing damage or poor colour payoff
- Applying colour to the scalp without checking for sensitivities
- Not timing the development correctly, resulting in over or under processing
- Failing to perform a skin test or not recording results, leading to potential allergic reactions or legal non-compliance.
- Choosing the wrong developer strength or colour formulation, resulting in incorrect lift or deposit, and damage to hair.
- Improper timing of colour processing, either rinsing too early for insufficient result or leaving too long causing scalp irritation or breakage.
- Failing to perform a skin test or incorrectly interpreting allergic reaction signs, compromising client safety.
- Using incorrect developer volume leading to unexpected colour results or hair damage.
- Overlapping colour during retouch applications causing banding and uneven colour.
- Failing to conduct a thorough porosity and elasticity test before application, leading to uneven colour uptake.
- Overlapping bleach or permanent colour onto previously lightened hair, causing breakage or banding.
- Neglecting to protect the client's skin and clothing adequately, resulting in staining or chemical burns.
- Failing to perform a skin sensitivity test at least 48 hours prior to service, leading to potential allergic reactions and non-compliance with insurance requirements.
- Overlapping colour applications on previously coloured hair, causing banding or uneven results.
- Neglecting to consider the underlying pigment of the client’s natural hair when selecting a target shade, resulting in unrealistic outcomes.
- Failing to perform a sufficient strand test to confirm colour outcome, leading to unpredictable results or client dissatisfaction.
- Assuming previous colour history without asking probing questions, causing colour overlap or chemical reactions.
- Neglecting to protect the client's clothing, skin, and the surrounding work area adequately from staining.
- Applying colour to the hairline first instead of the mid-lengths and ends when dealing with regrowth, resulting in uneven colour development.
- Failing to carry out a skin test or overlooking its validity period, risking allergic reactions and legal non-compliance.
- Incorrectly diagnosing existing hair colour and porosity, leading to unsuitable product choice and unexpected colour results.
- Not sectioning hair properly, causing uneven product distribution and patchy coverage.
- Over-processing by leaving colour on too long or using excessive heat, resulting in hair damage or client discomfort.
- Poor communication during the service, missing client feedback on developing colour and causing dissatisfaction.
- Omitting or incorrectly conducting a skin sensitivity test prior to service.
- Using incorrect developer strength leading to over-processing or undesired results.
- Failing to protect client’s clothing and skin, resulting in stains.
- Inadequate mixing of colour, causing uneven coverage.

- Not sectioning hair properly or applying colour too slowly, causing uneven processing or missed areas.
- Misinterpreting manufacturer's mixing ratios or processing times, which can compromise colour accuracy and integrity.
- Misconception: You only need to be good at practical skills to pass. Correction: The diploma also requires strong theoretical knowledge, such as understanding hair and skin biology, product chemistry, and legal obligations. Written assessments and online tests are equally important.
- Misconception: Health and safety is just common sense. Correction: While some aspects are intuitive, specific regulations like COSHH and RIDDOR must be memorised and applied correctly. Examiners look for precise terminology and evidence of following procedures.
