formula no5 hair growth serum
formulated to target all major hair growth deficiencies
stress
Chronic stress disrupts the hair growth cycle, prematurely pushing follicles into shedding phases.
- Helps support follicles impacted by elevated cortisol
- Reinforces the growth (anagen) phase under stress conditions
- Supports scalp balance during periods of physical or emotional stress
hormones
Hormonal fluctuations can interfere with follicle signaling and nutrient delivery to the scalp.
- Supports healthy follicle response to hormonal shifts
- Helps maintain optimal scalp signaling pathways
- Designed to reinforce growth during hormonal imbalance
menopause
Declining estrogen levels during menopause can weaken follicles and reduce hair density over time.
- Supports follicles affected by estrogen decline
- Helps improve hair shaft strength and thickness
- Designed for age-related density loss
postpartum
After pregnancy, hormonal drops can trigger widespread shedding known as postpartum hair loss.
- Supports follicles transitioning after pregnancy
- Helps normalize the hair growth cycle post-partum
- Reinforces regrowth during shedding recovery
aging
As we age, follicles shrink, growth slows, and hair becomes finer and less resilient.
- Helps counteract follicle miniaturization
- Supports cellular repair and regeneration
- Designed to maintain density and scalp vitality over time
alopecia
Certain forms of alopecia involve disrupted follicle signaling and inflammatory stress on the scalp.
- Supports weakened or compromised follicles
- Helps maintain a healthy scalp environment
- Reinforces growth pathways impacted by follicular stress
dehydrotestosterone (dht)
DHT can bind to follicles, gradually shrinking them and shortening the hair growth cycle.
- Helps protect follicles from DHT-related stress
- Supports normal follicle size and function
- Designed to maintain long-term growth signaling

faq
How does Formula 05 work?
Formula 05 works by delivering five clinically studied botanical actives to the scalp. Each one targets a different part of the hair cycle — waking dormant follicles, extending the growth phase, and slowing the signals that trigger shedding. Applied daily, they reach the follicle zone and support thicker, stronger, denser-looking hair over time.
How long until I see results?
Most people use 3-6 months of consistent use to see visible results, as hair growth cycles take time.
Is it safe to use every day?
Yes — it's formulated for daily use, morning or night, on wet or dry scalp.
Can I use it with other hair products?
Yes, it layers well with your existing hair care routine.
