If hair feels thinner, limp, or simply not as full as it once was, the Vegamour GRO+ Advanced System presents itself as a targeted solution. This comprehensive regimen — combining shampoo, conditioner, serum, and (in some iterations) supplements — is engineered specifically for shedding, scalp health, and improving visible density. Below is an in-depth exploration of the system: the science, the ingredients, the usage, the evidence, and practical take-aways.

What is the GRO+ Advanced System?

The GRO+ Advanced System from vegan hair-care brand Vegamour is a multi-step routine crafted for individuals with thinning hair, increased shedding, or scalp imbalances. It’s positioned as their most intensive “growth-support” offering, building on their original GRO line. According to the brand, this upgraded system is clinically proven to increase hair density and reduce shedding over a 3–4 month span. Vegamour+3Fashion IPA+3Never Say Die Beauty+3

Components typically include:

• A balancing shampoo (for thinning or shedding-prone hair)
• A balancing conditioner
• A topical serum (for direct scalp/folllicle intervention)
• Optionally: hair growth-&-density supplements
  Each product is vegan, cruelty-free, and formulated without silicones or synthetic fragrances (in the serum at least) according to manufacturer claims. Amazon+1

Why it may work: the key ingredients & mechanisms

1. Scalp environment & follicle priming

Healthy hair growth starts at the scalp level. The GRO+ serum, for example, contains the brand’s “GROActive+ Complex™” — described as an AI-selected blend of antioxidant-rich Rhapontic rhubarb root extract and Japanese BeautyBerry extract, designed to improve density and reduce shedding. Never Say Die Beauty+1
It also uses Spanish micro-algae (a pre-biotic superfood) to support scalp hydration and balance, plus plant stem cells intended to anchor follicles. Never Say Die Beauty+1

2. Botanical actives targeting shedding & DHT pathways

A few standout botanical ingredients:

• Red clover (Trifolium pratense) and mung bean (Vigna radiata) extracts appear in earlier GRO formulas. These may help support scalp health and mitigate DHT-related thinning. Cosmopolitan+2Lady Alopecia+2
• Turmeric root extract (Curcuma longa) appears in the advanced formula; known for its anti-inflammatory and antioxidant benefits. Never Say Die Beauty+1
• Caffeine: frequently used in scalp-care for circulation support and follicle stimulation. Vegamour

3. Strengthening + prolonging growth phase

Some formulations include peptides (e.g., Biotinoyl Tripeptide-1, Acetyl Tetrapeptide-3) as seen in the advanced serum’s ingredient list. These peptides can help encourage thicker strands and improve follicle health over time. Never Say Die Beauty+1

4. Clean, supportive base

The system is formulated to be vegan, cruelty-free, colour-safe, and free of silicones/fragrance in key items (particularly the serum) — which makes it more scalp-friendly for those with sensitivity or who use colour treatments. Amazon

User results: what the evidence and real users say

Clinical claims

According to Amazon listing for the advanced serum: “In a 120-day study, participants using GRO+ Advanced Hair Serum once daily saw a 93% clinically measured improvement in hair density and up to 87% reduction in hair loss due to breakage from washing and combing.” Amazon
Also claimed: 98% saw less shedding; 95% said they saw less hair in the shower; 95% said their scalp felt healthier. Never Say Die Beauty+1

While promising, it’s important to note that independent peer-review data is limited; results may vary considerably depending on hair type, cause of thinning, consistency of use, and other underlying factors.

Real-world reviews

• A review on Fashionipa found that within two weeks of consistent use of the shampoo/conditioner/serum system, the user noticed cleaning less hair from the shower and the stylist remarked on “a lot of new growth.” Fashion IPA
• A detailed blog on NeverSayDieBeauty (March 2025) documented about 70 days of use of the advanced serum; the reviewer felt shedding had stopped and small hairs were starting to regrow in temple areas. Never Say Die Beauty
• Cosmpolitan’s review of the original (non-Advanced) GRO serum found visible new baby hairs at about three months when used daily and applied to scalp. Cosmopolitan

How to use the system for the best effect

• Shampoo & Conditioner: Use the balancing shampoo 2-3x per week (or as your typical schedule allows), leaving it in for about 1 minute, then apply conditioner for 2 minutes before rinsing—per reported user methods. Fashion IPA
• Serum: Apply a full dropper (or as instructed) directly onto the scalp — part hair in sections for maximum coverage. Massage in. Can be used on wet or dry scalp. According to brand: apply daily for best results. Vegamour+1
• Supplements (if included/used): Use daily as directed. Supplements (where available) support internal follicle health and nutrient supply but are adjuncts, not replacements for topical/scalp treatments.
• Duration: Because hair growth cycles are slow, consistent use for 90-120 days is recommended to properly judge results. Especially critical when dealing with density and shedding. Never Say Die Beauty+1
• Complementary habits: Minimise heat damage, avoid over-processing, maintain a healthy diet, keep scalp clean and free of heavy build-up — these maximise the impact of any growth-support system.

Cons / Things to Consider:

• Cost: Premium pricing relative to standard shampoo/conditioner regimes. (Many users purchase bundles or multiple bottles to fully judge results.)
• Results tied to consistency: Skipping or inconsistent application will likely reduce effectiveness.
• Underlying cause of hair thinning matters: If hair loss is due to hormonal imbalance, medical condition (e.g., alopecia areata), or nutritional deficiency, a topical regimen alone may not resolve the root cause.
• No guarantee of full reversal of thinning: Some users report improvement, but not a return to original density. For example, one reviewer noted: “The recession of the hairline has definitely stopped and some thin hair has regrown, though my hair will never be as thick as it was when I was younger.” Never Say Die Beauty
• Supplements and topical actives may accelerate hair growth, but hair still grows at its natural phase-cycle pace, so visible changes take time.

Who is this system best for?

This system is most suited to individuals who:

• Notice recent increased shedding or thinning rather than long-standing bald patches.
• Have tried standard volumising/thickening shampoos without addressing the root scalp/follicle environment.
• Prefer a vegan/plant-based hair-growth support alternative.
• Are prepared to commit to daily use for several months and keep realistic expectations (density improvement rather than miraculous full hair restoration overnight).
• Use colour treatments or heat styling and want a system that is colour-safe and safer for processed hair.

It may be less ideal if:

• Hair loss is caused by advanced pattern baldness, underlying medical condition, or scarring alopecia — where medical treatments (dermatologist-directed) may be more appropriate.
• The budget does not allow for the premium cost of a consistent multi-month regimen.
• Expectation is immediate thickening or instantaneous “full hair return” — realistic results take time.
  

Practical tips for maximising results

• Start before major commitment: Take “before” photos of your scalp, ponytail circumference, shedding amount in shower/drain. Helps track progress and gives motivation.
• Apply to scalp, not just hair strands: The serum works at the root/follicle level — massaging it into the scalp ensures better absorption.
• Stay consistent: Daily serum + shampoo/conditioner on wash days is the core. Set a reminder if needed.
• Be patient: Hair density changes may become noticeable around the 8-12 week mark or beyond. Early signs may include less shedding rather than dramatic new hair growth.
• Watch for eyebrow or body hair effects: Some supplement users report growth in areas they didn’t expect — keep an eye and tweeze/trim as desired.
• Support from within: A balanced diet rich in protein, iron, zinc, biotin (from food sources) enhances external treatment effectiveness. Avoid tight styles or excessive heat damage that counteracts the efforts.
• Evaluate after 3-4 months: If little to no improvement after consistent use, consider consulting a dermatologist for further evaluation — thinning may require deeper investigation (hormonal, nutritional, genetic).

For those dealing with thinning hair or increased shedding and seeking a more serious hair-growth-support routine, the Vegamour GRO+ Advanced System presents a strong option. It marries scalp science, botanical actives, and a full-system approach that goes beyond shampoo-and-conditioner alone. The fact that it is formulated by dermatologists (per brand claims) and leverages clinical-style testing gives it an edge over generic hair-thickening products.

It isn’t a miracle overnight fix — hair growth takes time, and results depend on commitment, underlying conditions, and proper supporting habits. Nevertheless, if budget allows and the goal is fuller, healthier-looking hair over a few months, this system is well-positioned to deliver.

To summarise: commit to consistent use, manage expectations (improvement rather than full restoration), support with good hair-care habits, and track your own progress. If all boxes are ticked, results can be meaningful.
