"What's actually in this?" is one of the first questions worth asking about any hair growth product — and it's a fair one. With so many hair care claims on the market, it helps to know exactly which ingredients are doing the work, and why they're paired together the way they are. Here's a full, ingredient-by-ingredient breakdown of the Lustrao Hair Growth Trio — what's in each of the three steps, and the role each ingredient plays in supporting scalp health and hair growth.

Discover the Lustrao Hair Growth Trio — a 3-step shampoo, conditioner & regrowth oil system that cleanses, strengthens, and stimulates dormant follicles. Sulfate-free, silicone-free, and safe for all hair types.

The Growth Shampoo is formulated to cleanse without stripping — its sulfate-free base removes buildup while leaving the scalp's natural moisture barrier intact.
- Rosemary Oil — One of the most studied botanical actives for hair growth, rosemary oil is believed to improve scalp circulation, which in turn helps deliver more nutrients to hair follicles.
- Peppermint Oil — Works alongside rosemary to boost circulation, and gives the scalp a cooling, refreshing sensation that signals the product is actively working.
- Tea Tree Oil — A natural antimicrobial that helps keep the scalp clear of the buildup and flaking that can clog follicles over time.
- Lavender Oil — Calms scalp irritation and inflammation, which is especially useful for anyone prone to sensitivity or itchiness.
- Hyaluronic Acid — A powerful humectant that draws moisture into the scalp and hair, preventing the dryness that often comes with clarifying formulas.
- Vitamins C & E — Antioxidants that help protect the scalp from oxidative stress, one of the underlying contributors to premature follicle aging.
What's in the Lustrao Growth Conditioner
The Growth Conditioner focuses on repair and hydration — undoing the damage caused by daily styling, heat, and environmental exposure.
- Aloe Vera — Deeply hydrating and soothing, aloe vera helps calm the scalp while adding moisture back into dry strands.
- Tea Tree Oil — Reappears here to keep the scalp balanced even as the conditioner focuses on the hair shaft.
- Hydrolyzed Silk Protein — A lightweight protein that coats and reinforces each strand, improving elasticity and reducing breakage from brushing or styling.
- Orange Extract — Rich in vitamin C, orange extract supports shine and helps protect hair color and strength.
- Vitamins A & E — Support strand repair and add a protective, smoothing layer that helps reduce frizz.
What's in the Lustrao Hair Regrowth Oil
The Hair Regrowth Oil is the most concentrated, targeted step — designed to be left on the scalp to work over time.
- Rosemary & Peppermint Oil — The same circulation-boosting duo from the shampoo, but in a more concentrated, leave-on format for deeper impact.
- Panax Ginseng — Traditionally used to support scalp health and stimulate hair follicles, ginseng is often included in regrowth-focused formulas for its follicle-nourishing properties.
- Castor Oil — A thick, nutrient-dense oil rich in ricinoleic acid, known for improving scalp circulation and adding moisture to both scalp and strands.
- Argan Oil — High in vitamin E and fatty acids, argan oil nourishes the scalp barrier and adds shine without weighing hair down.
- Olive Oil — A classic moisturizing oil that helps seal in hydration and softens hair over time.
How the Ingredients Work Together
Each step is built to support a different part of the hair growth cycle:
- Shampoo clears the scalp so nothing blocks follicles from functioning properly.
- Conditioner repairs and strengthens the visible hair, reducing breakage that can make hair look thinner even when growth is fine.
- Regrowth Oil delivers the most concentrated actives directly to the scalp, where new growth actually starts.
This is why the trio is designed to be used together rather than as standalone products — each step removes a different barrier to healthy growth.
What's Not in It
Just as important as what's included is what's deliberately left out. The Lustrao Hair Growth Trio is formulated without sulfates, parabens, silicones, or mineral oil — ingredients commonly linked to scalp irritation, buildup, or long-term dryness in hair care formulas.

FAQ
Does research back these ingredients?
Rosemary oil, in particular, has been studied for its potential to support hair density, and peppermint oil has shown circulation benefits in early research. As with most botanical hair care, results vary by individual, and these ingredients work best as part of a consistent routine rather than a one-time fix.
Is the Hair Regrowth Oil safe to use every day?
The oil is designed for 2–3 uses per week, or as an overnight treatment. Daily use isn't necessary for results and may feel heavier on finer hair types.
Will these ingredients work for color-treated hair?
Yes — the formula is free from sulfates and harsh detergents that typically strip color, making it color-safe for chemically treated hair.
Can I use the shampoo and conditioner without the oil?
Yes, they're available as a 2-step Hair Growth Duo — though the oil adds the most targeted follicle-stimulating actives, so the full trio is recommended for anyone focused specifically on regrowth.
