Frequently asked questions
よくある質問
Q1 How fast does hair grow on average?
Human hair grows approximately 0.5 inches (1.25 cm) per month, or about 6 inches (15 cm) per year. This varies by genetics, age, diet, and overall health.
Q2 How do I measure my hair length accurately?
For straight hair, pull a strand taut from the root and measure to the tip. For curly hair, gently stretch a curl straight and measure — this gives your true length.
Q3 Can I speed up hair growth?
You can optimize growth by eating a protein-rich diet, reducing heat damage, using a silk pillowcase, and getting regular trims to prevent breakage.
Q4 What is the awkward stage of growing out hair?
The awkward stage hits between ear-length and chin-length (4-6 inches). Hair is too short to tie back but too long to style easily. This phase usually lasts 3-6 months.
Q5 How do I know which hair length suits my face shape?
Download the free Hairstyle AI app to try different lengths on your own photo before committing to a cut.
Q6 Does trimming hair make it grow faster?
Trimming doesn't affect growth rate, but regular trims prevent split ends from causing breakage, which helps you retain more length over time.
