The Ultimate Anti-Hair Fall System

Shop Kerastase Genesis

IT'S JUST A PHASE

PHASE 1

Stop the Fall

Every routine starts at the scalp. These products target the follicle directly — calming the trigger, re-anchoring weakened roots, and stopping the shed before it accelerates.

PHASE 2

Support Regrowth

Once shedding slows, your scalp needs to become a place new hair wants to stay. Stimulating treatments and density-building formulas create the environment your follicles need.

PHASE 3

Protect What's Growing

New growth is vulnerable. Hair that regrows after a shed is often finer, more porous, and more prone to breakage. This is where your Dense Era meets your Repair Era — keeping every strand strong.

Frequently Asked Questions

Need help finding an answer to your question? Ask our customer support at zennkai@megahairfamily.com

Can thinning hair grow back?

Yes. If thinning is caused by breakage, stress, scalp buildup, or hormones, density can often improve with the right professional routine.

How long does it take to see results?

Visible improvement usually takes 6–12 weeks of consistent use. Haircare systems work at the follicle and fiber level, gradually strengthening strands and improving density over time.

Is my hair thinning or breaking?

Most women experience breakage, not true hair loss. Breakage happens mid-shaft, while thinning comes from the root.

 

How often should I wash or treat thinning hair?

A balanced routine is key. Most thinning hair benefits from gentle cleansing 2–3 times per week, followed by strengthening or scalp treatments to protect and support growth without over-stripping natural oils. General rule of thumb: Oily scalps: 3–5x/week. Dry scalps: 1–3x/week

Do shampoos really matter?

Yes. Professional shampoos treat the scalp and hair fiber, not just clean the surface.

Will styling tools or heat make hair loss worse?

Excessive heat or harsh chemical treatments can increase breakage. Always use thermal protectants and gentle styling techniques to maintain healthy strands while achieving your look.

Can stress affect hair growth?

Yes. High cortisol can disrupt growth cycles and increase shedding.

Does aging affect hair thickness?

Yes. Hormonal changes after 40 can affect density and texture.

Can I use too many products?

Yes. Over-layering causes buildup and dullness. Proper layering is key.
