UnTangled Hair Supplement & Hair Serum vs. Vegamour GRO Hair Serum®
Purpose
The Foundation Skincare UnTangled Hair Supplement is crafted with clinically proven herbs, vitamins, minerals, and acids that nourish the hair follicles, help increase the production of keratin, and revitalize the hair growth cycle. With regular use, this dermatologist formulated solution works to promote stronger, denser hair.
The dermatologist-formulated Foundation Skincare Hair Serum is a topical product that was made for men and women dealing with hair loss, thinning, or shedding that are looking for a minoxidil-free hair growth remedy. It has been proven to stimulate the hair stem cells and root, helping to promote fuller and healthier hair. This solution also nourishes the hair cuticle to prevent breakage.
Vegamour’s GRO Hair Serum® is also a topical solution. The clinically-tested formula is designed for women looking to reverse thinning hair, and uses the power of phytoactives to soothe the scalp and revitalize the follicles to help improve hair density and reduce shedding. Vegamour also offers a variety of other hair growth products, including oral supplements and bundles, though the comparison below will focus only on its topical hair serum.
Ingredient Breakdown
The FS UnTangled Hair Supplement is made with ingredients that promote circulation and fortify the follicles, including vitamin C, marine collagen, horsetail extract, folic acid, and iron. Saw palmetto also helps reduce dihydrotestosterone (DHT, a hormone often tied to hair thinning), while vitamins A and E defend against free radical damage. Certain vitamins and minerals tied to hair loss,including biotin, iron, zinc, selenium, and vitamin D, are also included in the formula to target nutritional deficiencies.
The FS Hair Serum is powered by proven ingredients like Stimucap,which restores the hair follicles to prevent loss, and Capixyl, a complex of biomimetic peptide and red clover extract that may help support hair growth and inhibit DHT-related follicle miniaturization. Saw palmetto also inhibits DHT, while apple stem cells nourish.
The Vegamour hair serum is made with curcumin stem cell and red clover extracts, both of which work to block the negative effects of DHT. Copper-rich mung bean helps strengthen the follicles, while caffeine and biotin stimulate growth.
How to Use Them
As is the case with any hair growth product, consistency is key. With the FS UnTangled Hair Supplement, you should take two capsules each day, ideally one in the morning and one in the evening.
The FS Hair Serum should be applied to dry hair, ideally after shampooing but before applying other hair products. Apply the leave-in solution directly to the scalp, gently massaging in each drop as you go. It can be used twice a day (morning and night) for the best results.
The Vegamour GRO Hair Serum® can be applied to either towel-dried or dry hair, and can be used once a day (either morning or night). Like the Foundation Skincare serum, this solution is designed to be gently massaged into the scalp.
Results
For the Foundation Skincare products, you can see results by using them on their own, but you can maximize your hair growth potential by using them in tandem. This combined approach helps target hair loss, while supporting overall hair and scalp health from multiple angles. With consistent use of both products, you can expect to begin seeing new growth around the 30-day mark, and achieve visibly fuller, stronger hair after 90 days.
For the Vegamour GRO Hair Serum®, the company states that users may begin to notice fuller hair after 90 days. The full results should be achieved after 120 days of using the solution consistently.
The Bottom Line
Both Foundation Skincare and Vegamour offer well-formulated solutions to support thicker, healthier hair, but they differ in approach, timeline, and long-term value. Here’s a quick breakdown of the key similarities and differences:
-
Foundation Skincare targets hair growth from the inside and out. By combining a supplement with a topical serum, it supports follicle health, nutrient intake, and scalp condition all at once.
-
Vegamour’s GRO Hair Serum® focuses on topical support. It’s designed to revitalize the scalp and improve the appearance of fuller hair, but doesn’t provide the same internal nutrient support on its own.
-
Timelines can vary depending on the approach. With consistent use, Foundation Skincare users may begin seeing changes around 30 days, while Vegamour’s serum typically shows visible results closer to 90 days.
-
Both options use ingredients that support follicle health. Each formula includes compounds that help strengthen hair and address factors like DHT-related thinning.
-
Cost and consistency can make a big difference over time. Foundation Skincare’s Hair Serum is $45 for a one-time purchase (or under $40 with a subscription) for a 2 oz bottle, while Vegamour’s GRO Hair Serum® is $64 one-time or $49 with a subscription for 1 oz.
-
Bundled systems may offer more value long-term. The UnTangled Essentials Kit includes a 60-day supply of supplements and two full-size serums, making it a more cost-effective option for maintaining a consistent routine.
Ultimately, if you’re looking for a simple, comprehensive system that supports hair growth from multiple angles, Foundations Skincare offers a more streamlined and cost-efficient approach. If you prefer to stick with a topical-only route, Vegamour’s GRO Hair Serum® can still be a solid option with consistent use.
