Specifications
Hair Type: Natural / untreated hair, experiencing progressed thinning. Fine to medium natural hair.
Strengthens Hair & Reduces Breakage — by nourishing roots, reducing follicle‑clogging, and offering resilience.
Improves Scalp Health — the shampoo helps remove sebum, environmental residues; treatment nourishes.
Refreshes, Feels Clean — peppermint / wild mint gives a cooling feel; cleansing helps with impurities.
Colour Safe — since it’s for natural, untreated hair, the concern for preserving color is less, but still formulated to be gentle. (Though there are other kits more specialized for coloured hair.)
Why Choose System Kit 2?
You might select this kit if:
You have natural hair (i.e. not heavily dyed, permed, bleached) and notice progressed thinning — meaning thinning is more than just very mild; perhaps you see scalp through the hair, or your hair feels less dense.
You want a regimen that combines cleansing + conditioning + leave‑on treatment rather than just washing or topical only.
You’re looking for something that improves fullness/volume and scalp health together.
You prefer botanicals + scientific/clinical formulation (with caffeine, biotin, niacinamide etc.) rather than just natural/herbal remedies.
Things to Be Aware Of / Possible Drawbacks
Some users report dryness after use, especially if using frequently, or if hair is fine. The strong cleansing & active ingredients may strip moisture.
You may notice increased shedding initially. This is sometimes expected when follicles are cleared and hair cycles reset.
If you have a sensitive scalp, peppermint / mint oils and salicylic acid might cause tingling, burning, or irritation. Patch testing may help.
It’s a premium product set; cost can add up if you keep using all three products regularly.
How To Use
Step 1 – Cleanse (Shampoo): Wet hair thoroughly, apply the shampoo to scalp, massage gently to work up a lather, let sit ~1 minute to allow active ingredients (e.g. salicylic acid, mint oils etc.) to act, then rinse.
Step 2 – Condition: Apply the System 2 Conditioner from roots to ends (including scalp; the formula is lightweight), leave‑in for 1‑3 minutes, then rinse thoroughly.
Step 3 – Leave‑in Treatment: After towel drying, apply the treatment to scalp and hair (roots especially). Massage in. Do not rinse. Then style as usual. UV protection is provided here.
Frequency: Use the full 3‑step system at least 3 times per week for visible results; many sources suggest daily or near‑daily usage for best outcomes.
