Every formula, technique, and tool decision begins with one thing: information. Without a thorough understanding of the client’s hair history, even the most skilled stylists risk unexpected results. A solid consultation isn’t a quick chat—it’s a diagnostic process. And like any diagnostic tool, a checklist brings consistency, depth, and clarity.
Use the following categories to build a hair history profile that supports safe, effective service planning—especially for color, smoothing, and chemical treatments.
1. Color Application History
-
When was the last color service?
-
Was it done professionally or at home?
-
What type of color was used (permanent, demi, direct dye, box dye)?
-
Are there layers of overlapping color from past applications?
This section uncovers fading patterns, possible banding, and reactivity risks. It also sets realistic expectations for lift and tone.
2. Chemical Service History
-
Has the client had any keratin, relaxer, perm, or chemical smoothing service?
-
What brand or type was used, and when?
-
Was it done on virgin or previously processed hair?
Chemical layering—especially when undocumented—can lead to breakage, uneven porosity, and unpredictable color behavior. Knowing what's on the hair avoids catastrophe.
3. Scalp and Sensitivity Indicators
-
Any history of itching, burning, or allergic reactions during services?
-
Does the client experience frequent flaking, tightness, or excess oil?
These answers influence product selection and service adjustments. Scalp sensitivity should never be discovered mid-application.
4. Medication and Health Factors
-
Is the client currently on medication that could affect hair (e.g., hormone therapy, acne treatments, antidepressants)?
-
Any recent illness, surgery, or major hormonal shifts?
Certain medications can alter hair texture, growth cycle, and color receptivity. This is especially critical in pre-lightening and thinning scenarios.
5. Daily Routine and Environmental Exposure
-
What does their wash and style routine look like?
-
Do they swim, work in the sun, or wear hats regularly?
-
Are they using any over-the-counter products with high alcohol or protein content?
This section gives insight into buildup, dryness, and how the hair behaves between services.
6. Past Problem Services
-
Have they ever had a service that went wrong?
-
What did they dislike about past results—color, tone, cut shape, texture?
Understanding their pain points prevents repeating mistakes and establishes trust.
7. Commitment Level and Maintenance Goals
-
How often do they return for appointments?
-
Are they open to at-home maintenance or prefer low-effort routines?
Matching the service to their lifestyle keeps retention high and dissatisfaction low.
A hair history checklist doesn’t slow down the consultation—it sharpens it. Stylists who standardize their intake process are better equipped to problem-solve, plan, and deliver results with confidence. Hair tells a story, but only if you know how to ask the right questions.
