Post-chemotherapy regrowth: how to speed the return to a dense, even head of hair
When healing continues beyond treatment
Chemotherapy is an essential step in recovery, but it often leaves a visible mark: hair loss. While regrowth naturally begins a few weeks after the end of treatment, returning to dense, even and resilient hair is a long and uneven process.
It is precisely to support this reconstruction phase that the RENASCOR Laboratory, a world expert in post-oncological hair regrowth, has developed a unique approach, validated by clinical experience and supported by research.
Understanding post-chemotherapy regrowth
Cytotoxic agents target rapidly renewing cells — including those of the hair follicle. The result: the hair bulb is weakened, its growth cycle interrupted, and the scalp compromised.
After the end of treatments:
-
The anagen phase (growth) restarts, but in an irregular way.
-
Some follicles produce fine or depigmented vellus hair, others remain dormant.
-
The scalp may show dryness, flaking, hypersensitivity or micro-lesions.
It is this combination of imbalances that the REDACTIV1 / REDACTIV2 protocol from the RENASCOR Laboratory was designed to correct.
A unique scientific expertise worldwide
The RENASCOR Laboratory is today the only laboratory in the world to focus its research exclusively on post-cancer hair reconstruction.
Its work is based on the study of post-cytotoxic follicular mechanisms and on regenerative cellular bio-stimulation, in order to reactivate dormant follicles without damaging the scalp.
The REDACTIV1 and REDACTIV2 treatments are based on three complementary lines of action :
-
Repair the scalp micro-environment
→ restoration of the hydrolipidic film, soothing, cellular healing. -
Reactivate the anagen cycle
→ stimulation of bulge follicle stem cells, homogenization of regrowth. -
Strengthen the fiber and maintain density
→ bio-active nutrition of emerging hair, long-lasting antioxidant and anti-inflammatory protection.
REDACTIV1: restart the scalp's cellular life
First treatment of the course, REDACTIV1 prepares the ground for regrowth.
Its concentrated formula promotes micro-healing of the epidermis, deeply hydrates and stimulates the first signs of anagenesis from the 2nd week of application.
It is used daily on a clean scalp, from the 10th day after the end of chemotherapy (or after hair transplant).
Visible benefits :
-
Immediate relief from tightness and itching,
-
Emergence of uniform vellus hair,
-
Reduction of thinning areas and chaotic regrowth.
REDACTIV2: densify, even out, strengthen
After the restart phase, REDACTIV2 takes over to accelerate densification.
Its patented combination of botanical actives, biomimetic extracts and plant growth factors stimulates the production of high-quality keratin and stabilizes the hair cycle.
Goal : achieve dense, even and resilient regrowth, for a lasting return to a full head of hair.
An integrated method in socio-aesthetic protocols in oncology
RENASCOR treatments are now recommended and used in many hospital centers and oncology units.
Their efficacy and tolerance have led many socio-aestheticians to integrate them into their post-chemotherapy reconstruction protocols, alongside medical follow-ups.
This field-laboratory collaboration has allowed the textures, dosages and optimal treatment durations to be perfected for each patient profile.
Testimonial from a professional :
"The patients I support notice a real difference from the first weeks: a soothed scalp, hair coming back to life. The RENASCOR protocol restores confidence and comfort at a time when self-image is essential."

RENASCOR Laboratory's tips to optimize regrowth
-
Avoid any coloring or perm before 3 months of stable regrowth.
-
Prefer thes gentle sulfate-free shampoo and free of harsh agents from the RENASCOR range.
-
Gently massage the scalp for 1 to 2 minutes per day to stimulate microcirculation with the REDACTIV serum suited to your hair situation.
-
Maintain a diet rich in protein and iron (essential factors for keratinization).
RENASCOR, pioneer in post-cancer hair reconstruction
Every day, the scientific teams at the RENASCOR Laboratory continue their research to improve the quality of regrowth after chemotherapy and restore the confidence of thousands of patients worldwide.
Our mission is clear: to support recovery all the way to the mirror.
