Your Hair Restoration Journey

What you can expect in the coming weeks with daily HairLab application.

Initial state
Baseline

Active Shedding

Hair roots are weakened due to DHT buildup, causing follicles to shrink and hair to shed excessively. Shafts feel weak and thin.

Weeks 1-4

Reduced Shedding

Caffeine blocks DHT locally, stopping excessive hair loss. Active Biotin and oils nourish roots, stabilizing hair anchoring.

Weeks 1-4
Weeks 4-8
Weeks 4-8

Reactivation Phase

Dormant follicles are stimulated back into the growth (anagen) phase. You will notice fine new baby hairs along the hairline and crown.

Weeks 8+

Thicker Density

New hair shafts mature and thicken. Overall hair volume, density, and scalp coverage improve visibly. Maintain daily use for lasting results.

Pure, Target-Driven Growth Ingredients

Every bottle of HairLab features high-potency ingredients clinically validated for follicular support.

Biotin (Vitamin B7)

Promotes keratin synthesis, improving hair elasticity and overall shaft thickness while preventing premature breakage.

Keratin Boost

Caffeine

Blocks the harmful effects of DHT on hair follicles in the scalp, reversing hair shrinkage and extending the active growth cycle.

DHT Blocker

Rosemary Oil

Stimulates micro-circulation in scalp capillaries, supplying oxygen and amino acids directly to the hair matrix.

Capillary Booster

Castor Oil

Rich in ricinoleic acid, providing key moisture and sealing the hair shaft to prevent environmental styling damage.

Deep Hydration

Keratin & Collagen

Rebuilds structural gaps in thin hair shafts, creating immediate natural volume, bounce, and shine.

Shaft Repair

Ginseng Extract

Stimulates dermal papilla cells in follicles, facilitating cell multiplication to initiate new hair growth cycles.

Root Stimulator

Vitamin E

A powerful antioxidant that shields scalp cells from oxidative stress, maintaining a healthy follicle environment.

Scalp Shield

Panthenol (Pro-Vitamin B5)

Draws moisture deep into hair follicles and fibers, preventing dryness and flaking while improving manageability.

Moisture Seal

"In trichology, we target the hair follicle root. DHT accumulation is the primary cause of follicle shrinkage and eventual hair loss. HairLab's combination of local Caffeine to block DHT, combined with Biotin and Rosemary Oil to stimulate micro-circulation, provides an excellent, non-greasy, drug-free therapy. I recommend this spray to my patients experiencing early-to-moderate thinning as a safe daily routine."

Frequently Asked Questions

Want to know more? Here are answers to the questions our customers ask most.

How long until I see results?
Most users experience stabilized hair loss (significantly less shedding) in 2-3 weeks. New, fine baby hairs usually appear around weeks 6-8. Full aesthetic improvement in density and thickness takes about 90 days.
Is HairLab safe for color-treated hair?
Yes, HairLab is 100% drug-free, silicone-free, and sulphate-free. It does not affect dyes, highlights, or keratin treatments.
How should I apply the spray?
Apply 4-6 sprays directly to thin or shedding areas of the scalp daily (wet or dry hair). Massage gently for 1 minute to assist absorption. Do not rinse out immediately; leave it to absorb.
Are there any side effects?
No. Unlike drug-based solutions, HairLab uses cosmetic, botanical, and vitamin ingredients that do not cause scalp irritation, itching, or rebound shedding if discontinued.
How does the 90-day guarantee work?
If you use HairLab consistently for 90 days and do not see a reduction in shedding or an improvement in thickness, simply email [email protected] to request a full refund of your purchase.
