Hair fall reduction | Hair regrowth visibility | Scalp health improvement | Fragrance and comfort satisfaction
Data Collection Instrument:
A structured questionnaire was used both before and after the 3 months. Each variable was rated using a 5-point Likert scale (1 = Strongly Disagree, 5 = Strongly Agree).
Variables:
Hair Fall Reduction (HFR): “I experienced reduced hair fall after 3 months.” | Hair Regrowth (HRG): “I noticed new hair growth after consistent use.” | Fragrance Satisfaction (FS): “I like the herbal fragrance of the oil.” | Scalp Comfort (SC): “The oil did not cause itching or irritation.” | Texture & Absorption (TA): “The oil absorbed well and was non-sticky.”| Overall Satisfaction (OS): “I am satisfied with the overall product performance.” | Gender (GEND): Male = 1, Female = 2 | Age (AGE): Completed years | Frequency of Use (FREQ): Applications per week | Hair Fall Count Before (HAIRFALL_PRE) and After (HAIRFALL_POST)
6. Hypotheses
- H₀₁: There is no significant difference in mean hair fall count before and after using Growv Naturals Herbal Hair Oil.
- H₁₁: There is a significant reduction in hair fall count after 3 months of use.
- H₀₂: There is no significant relationship between gender and product satisfaction.
- H₁₂: There is a significant difference in satisfaction level between male and female participants.
7. SPSS Statistical Tools & Tests
- Paired Sample t-Test was used to compare hair fall before and after usage. A significant mean difference indicates product effectiveness.
- Independent Sample t-Test / Mann-Whitney U test was used to assess gender-wise satisfaction. A significant p-value (<0.05) indicates gender effect.
- Pearson Correlation was used to measure the relationship between usage frequency and hair regrowth. A higher r value indicates a stronger relationship.
- Multiple Regression (Dependent Variable = OS; Independent Variables = HFR, HRG, FS, SC, TA) was used to identify key predictors of overall satisfaction.
- Cronbach’s Alpha was used to determine overall reliability. Alpha ≥ 0.7 indicates high internal consistency.
8. Participant Observations and Improvements
Hair fall reduction: Visible reduction within 4–6 weeks, average improvement 78%.
Hair regrowth: New baby hairs observed on scalp, average improvement 72%.
Hair shine & texture: Smoother, healthier hair, average improvement 84%.

Overall satisfaction: Majority willing to repurchase, average improvement 88%.
Individual participants reported outcomes such as softer strands, reduced dandruff, improved scalp texture, visible regrowth, non-sticky absorption, and pleasant fragrance. Both male and female participants reported consistent improvements.
9. Expected Statistical Results
- Paired t-Test (Pre vs Post Hair Fall): Mean difference = -34.6 strands, p = 0.000 (<0.05), indicating significant improvement.
- Gender t-Test (Male vs Female OS): Mean difference = 0.18, p = 0.214 (>0.05), indicating no significant difference.
- Correlation (Usage Frequency vs Regrowth): r = 0.652, p = 0.001 (<0.05), indicating strong positive correlation.
- Regression (Predictors of OS): R² = 0.76, p = 0.000, indicating high predictability of satisfaction from HFR, HRG, FS, SC, TA.
- Cronbach’s Alpha (Reliability): α = 0.892, indicating highly reliable scale.
