A routine that fits into your day

A few minutes with the Combo System, six minutes under the cap. At home, on the sofa, before work.

What's in the Combo System

Three steps. One system.

KeraFactor Scalp Stimulating Solution

Scalp Stimulating Solution

A concentrated 50 ml solution with KFP™: growth factors and peptides wrapped in nano-liposomes, designed to help "turn on" weak or resting follicles.

KeraFactor Scalp Stimulating Shampoo and Conditioner

Shampoo & Conditioner

Exfoliates and revitalises the scalp with growth factors, caffeine and copper peptide, for hair that looks fuller with more body. Lasts at least a month.

KeraFactor Scalp Stimulating Brush

Scalp Stimulating Brush

Soft, contoured bristles that lift debris and boost circulation as you massage the products in.

+13.8%
thicker hair strands at 6 months

Clinical case report · 2026
Dr. Christie Kimball, MD

A woman with long-term thinning that had not responded to earlier treatments saw steadily increasing hair density.

Group averages, measured from baseline. Density (hairs per area) and diameter (thickness of each strand) are separate outcomes. The studies combined in-clinic laser treatment with KeraFactor home care; the home routine alone was not measured, and individual results vary.

The results in the studies came from combining in-clinic treatment with KeraFactor home care. Certified KeraFactor clinics offer the professional protocol, with a personal consultation and follow-up.

  • Personal assessment of your hair and scalp
  • Combine with the Combo System and a KeraFlex cap at home
Recommended protocol
  1. 4–6 clinic treatmentsA gentle laser combined with KeraFactor’s proprietary In-Office Serum, with your clinic planning the interval.
  2. Daily home careKeraFactor Scalp Stimulating Solution and Shampoo & Conditioner, the products in the Combo System.
  3. Red light therapyIn the Hamburg study, the group that also received red light had the largest density gain at one month.

How to use

A daily ritual that takes minutes

Cleanse

Lather a pea-sized drop of Shampoo & Conditioner into the scalp. Leave for 1 minute, then rinse.

Apply

Use one full dropper of Solution on wet or dry hair, morning or night, directly on the scalp.

Massage

Work it in with the brush using small circular movements. The scalp should turn a light pink, never red.

FAQ

Good to know

Do I get the Combo System for free with a laser cap?

Yes. When you buy the KeraFlex Laser Cap or the KeraFlex Duo, the KeraFactor Combo System is added to your cart for free.

What is the difference between the KeraFlex Laser Cap and the Duo?

The KeraFlex Laser Cap has 302 laser diodes at 650 nm (red light). The KeraFlex Duo has 312 diodes and adds 808 nm near-infrared light, which reaches deeper into the scalp. Both use 6-minute sessions.

Is KeraFactor clinically studied?

Yes. KeraFactor's growth factor formula has been studied in a randomized, controlled, evaluator-blinded pilot study at University Medical Center Hamburg-Eppendorf, published in Lasers in Medical Science (2026), and in a peer-reviewed pilot study in the USA (2022). In both, patients used the Scalp Stimulating Solution and Shampoo at home alongside in-clinic laser treatment.

Where can I get the in-clinic treatment?

The KeraFactor In-Clinic Treatment, a gentle laser combined with KeraFactor’s proprietary In-Office Serum, is offered by certified clinics. We recommend 4–6 treatments combined with daily home care. Use our clinic finder to find one near you.

Do I need a laser cap to use the Combo System?

No. The Combo System is a complete routine on its own. A KeraFlex cap is an optional upgrade for those who want to add light therapy.

How long does the Combo System last?

Only a small amount is needed each time. The 100 ml Shampoo & Conditioner lasts at least one month of daily use.

Will the KeraFlex cap fit my head?

The caps are made of flexible, comfort-fit materials. The opening is about 8 × 7 inches and flexes to fit a wide range of head sizes.

Individual results vary. If prolonged redness or irritation occurs, stop use.
