Growth Progress Chart
The Salonity Hair Growth Calculator gives you a fast, personalized estimate based on your age, gender, and hair type—helping you plan a realistic styling and hair-care journey with confidence.
Whether you are growing out a short cut, recovering from hair fall, or preparing for a new look, this tool shows how much length you can expect using evidence-based average growth rates plus adjustment factors.
What Is the Salonity Hair Growth Calculator?
It is a smart, personalized estimator that projects your potential hair length over a selected duration. Instead of relying on a single generic number, it adapts to:
- Age
- Gender
- Hair Type (straight, wavy, curly, coily)
- Growth duration in months
This produces more realistic timelines for planning trims, styles, and goals.
How Fast Does Hair Grow?
Average growth is about 1.27 cm (0.5 inches) per month, or roughly 15 cm (6 inches) per year. Your actual rate varies by genetics, nutrition, hormones, scalp health, and texture. The calculator applies gentle multipliers to approximate these influences.

What Affects Hair Growth Speed?
- Age: Growth may slow after 40 as follicles miniaturize.
- Gender: Androgen levels can slightly influence rate.
- Hair Type: All textures grow from the root similarly; curl/coil pattern creates visual shrinkage.
- Nutrition: Protein, iron, biotin & zinc deficiencies reduce synthesis.
- Stress & Sleep: Chronic stress can push follicles into resting (telogen) phase.
- Scalp Health: Balanced, clean scalp improves anchoring and cycling.
Why Use the Salonity Hair Growth Calculator?
Plan with data—not guesswork. Ideal for:
- Growing out a pixie, bob, buzz or undercut
- Preparing a bridal or long-style timeline
- Tracking regrowth post shedding (postpartum, illness, treatments)
- Estimating beard growth (future add‑on)
- Avoiding over-trimming and length setbacks
- Scheduling trims at optimal intervals
When Should You Trim While Growing?
Trimming does not accelerate growth, but preserves ends and prevents breakage—helping you retain length.
Straight
Every 10–12 weeks
Wavy
Every 8–10 weeks
Curly
Every 6–8 weeks
Coily
Every 6–8 weeks
The calculator can guide when your next trim aligns with target length retention.
Hair Growth Timeline – What to Expect
- After 1 Month: Subtle root lengthening; edges start extending.
- After 3 Months: Noticeable accumulation—layers soften, fringe grows out.
- After 6 Months: ~3 inches (~7.6 cm) added; transition to medium styles.
- After 12 Months: ~6 inches (~15 cm) added; strong foundation for long looks.
Re-check with the calculator every 4–6 weeks to track personalized progression.
Frequently Asked Questions
How much does hair grow in 2 weeks?
Roughly 0.6 cm (0.25 inches) on average. Hair growth rate varies by individual genetics, nutrition, and overall health.
How much does hair grow in a month?
Typically about 1.27 cm (0.5 inches) per month. This is the average rate for human scalp hair, though individual results may vary based on age, gender, hair type, and health factors.
How long does it take to grow 6 inches of hair?
Approximately 12 months for 6 inches of hair growth, subject to health and genetics. The Salonity Hair Growth Calculator can provide a personalized estimate based on your specific factors.
Can I speed up hair growth?
You can support optimal hair growth with protein intake, balanced micronutrients (biotin, iron, zinc), regular scalp massage, limiting heat and chemical damage, and consistent deep conditioning. While you cannot dramatically speed up the natural growth rate, you can optimize conditions for healthy growth.
Does trimming make hair grow faster?
No, trimming does not make hair grow faster. Hair growth originates at the follicle in the scalp. However, regular trims reduce split ends and breakage, helping you retain more length over time.
What factors affect hair growth speed?
Hair growth speed is influenced by age (growth slows after 40), gender (hormonal differences), hair type (curl pattern affects appearance), nutrition (protein, biotin, iron, zinc), stress levels, sleep quality, and scalp health.
Salonity Recommendations for Healthier Growth
- Use sulfate-free shampoo and gentle cleansing cadence
- Apply nourishing oils (coconut, castor, argan) as needed
- Deep condition weekly (adjust for low/high porosity)
- Prioritize protein + vitamin-rich diet (lean protein, leafy greens)
- Reduce stress via quality sleep & hydration
- Maintain scalp cleanliness and balanced sebum
Consistent implementation often shows visible improvements in 6–12 weeks.
