If growing your hair longer and stronger is the goal, figuring out when to cut hair for growth can feel just as important as the products you use or how often you trim. For generations, people have followed specific timing methods, often linked to natural cycles, to make the most of each haircut. While these traditions aren’t rooted in science, many still swear by them as a way to support healthier-looking hair and stay consistent with their growth goals.

When to Cut Hair for Growth/Moon Phase to Cut Hair for Growth #1. Waxing Moon Phase (New → Full Moon)
Many traditions that follow lunar timing say this is the best period to trim or cut hair if you want stronger, faster growth. This is the phase when the moon appears to grow bigger in the sky. People who use lunar calendars for haircuts often suggest scheduling trims right after the new moon up until the full moon for length-focused growth.
When to Cut Hair for Growth #2. Full Moon
Some calendars and enthusiasts suggest that cutting hair during the full moon can help with thickness and vitality.
It’s often seen as a midpoint in the lunar cycle that brings a boost of energy and volume to hair.
Best Time to Cut Hair to Discourage Growth #3. Waning Moon (Full → New Moon)
People who follow traditional lunar timing sometimes choose this phase when they want to maintain a hairstyle for longer rather than promote rapid growth.
It’s believed the hair will grow more slowly but may feel healthier with fewer split ends.
When to Cut Your Hair for Rapid Growth #4. Day-of-Week Beliefs
Certain cultural beliefs also suggest specific days of the week are more auspicious than others for general grooming:
- Some traditions say Wednesday or Friday might be good for clarity, beauty, or confidence with a haircut.
- Other traditional calendars caution against cutting hair on Mondays or Tuesdays, though these are rooted in astrology or folklore rather than biology.
What Hair Professionals Actually Say About the Best Time to Cut Hair for Growth
From a modern hairstyling perspective, hair growth is mostly determined by genetics, overall health, diet, and how often you trim to manage split ends.
Regular trims can help hair look healthier and avoid breakage, which gives the impression of faster growth because the hair isn’t breaking off.
There’s no strong scientific link that cutting hair on a specific day of the week or lunar phase actually makes it grow faster in length.

Best Day to Cut Hair for Growth Snd Thickness in January 1926 Pictures of Men
Here’s a clear guide to the best days to cut your hair in January 2026 if your goal is growth and thickness, based on widely shared lunar calendar timing that many people follow:
Best Days for Growth and Thickness
- January 13–15 and 21–24 are often listed as days when a haircut can support faster-returning hair after a trim — great if you’re planning a growth focus.
- Some lunar guides highlight January 25–26 as particularly strong for thickness and durability, thanks to the moon in Taurus — a sign traditionally associated with strength and density.
- Other sources suggest days early in the month like January 1 and 7 can be favorable for growth and strength, especially if you want a fresh start to the year.
Days to Avoid Cutting for Growth or Thickness
- January 3 and January 18 (moon phases like full or new moon) are often mentioned as times to skip haircuts because energy is traditionally considered low or unstable for growth.
- Some calendars also treat certain mid-month dates as less favorable for strong regrowth, so it’s good to cross-check your specific region or calendar if you’re watching lunar timing.
Quick Tips on Using These Days
- People who follow lunar timing typically prefer to schedule trims or growth-focused haircuts when the moon is waxing (between new and full moon) because this phase is associated with increase and strength.
- If you’re choosing a haircut day simply for routine maintenance or style rather than energetic timing, you can still pick a day that works with your schedule and check with your stylist about healthier growth habits.
