If you have noticed more hair in your brush, your drain, or your pillow since starting a GLP-1 medication, you are not imagining it. Shedding is a frequently reported and rarely discussed response to rapid weight loss. It typically appears two to three months after the loss begins, which is why so few people connect it to their medication. TAKE Regrowth is a lightweight nightly scalp serum built around five cosmetic peptide ingredients, with every ingredient disclosed below and the evidence behind each one graded honestly.
Before You Take Regrowth
If you are pregnant, nursing, or trying to conceive. This formula contains saw palmetto, which competitively inhibits 5-alpha reductase. It is not suitable for you. Speak to your provider first.
If you have a soy or wheat allergy. This formula contains soybean germ extract and wheat germ extract. If you avoid topical wheat protein, this is worth knowing before you order.
Hair Changes During Weight Loss Are Common. They Are Worth Understanding.
Rapid weight loss can cause increased shedding and visible hair thinning. It is a usually temporary, well-documented response to rapid body change, frequently reported during GLP-1 treatment, and rarely discussed.
It is a physiological response, not a cosmetic one. Metabolic and nutritional stress during rapid body composition change is a known contributor, and the result is shedding that typically appears two to three months after weight loss begins, which is why many people do not connect it to their medication until well after it starts.
TAKE Regrowth was formulated to support scalp health and the conditions that make healthy-looking hair possible.* Every ingredient in this bottle is named below, with the evidence behind it graded honestly. That is rarer in hair care than it should be.

All Five Peptides Named and Disclosed
Made in an FDA-Registered US Facility
The Five Peptides, And What We Do Not Claim
Listed in the order they appear on the label, which is descending order of concentration. Four are recombinant analogues of human growth factors. The fifth is a signalling protein rather than a growth factor, and we say so.
sh-Polypeptide-11 (aFGF)Acidic Fibroblast Growth Factor, also called FGF-1. Included as a cosmetic conditioning ingredient. Human evidence for topically applied growth factors and hair is not established, and we do not claim it.
sh-Polypeptide-1 (bFGF)Basic Fibroblast Growth Factor, also called FGF-2. Included as a cosmetic conditioning ingredient.
sh-Oligopeptide-2 (IGF-1)Insulin-like Growth Factor 1. Included as a cosmetic conditioning ingredient.
sh-Oligopeptide-10 (CCL2)Chemokine Ligand 2. A cell signalling protein rather than a growth factor, included as a cosmetic conditioning ingredient. We are naming it accurately rather than counting it as a growth factor, because it is not one.
sh-Polypeptide-9 (VEGF)Vascular Endothelial Growth Factor. Included as a cosmetic conditioning ingredient.
A correction we have madeEarlier versions of this page identified these five peptides as EGF, bFGF, IGF-1, KGF and VEGF. That was not accurate. EGF is sh-Oligopeptide-1 and KGF is a different INCI name again, and neither appears on this label. The list above is what the label actually contains, checked ingredient by ingredient. We would rather correct this in public than leave it standing.
Botanical And Amino Acid Support
Rosemary ExtractThe most studied botanical in this formula. One six-month randomized trial in 100 people with androgenetic alopecia compared rosemary oil with minoxidil 2%. Both groups gained hair count from their own baseline, neither outperformed the other, and there was no placebo arm. That trial used rosemary oil, while this formula uses rosemary extract.*
Saw Palmetto and EucalyptusSaw palmetto is included for its traditional role in hair and scalp formulations. It competitively inhibits 5-alpha reductase, which is why this formula is not suitable if you are pregnant, nursing, or trying to conceive. Eucalyptus is included for scalp comfort.*
ArginineAn amino acid included to support the appearance of hair strength and resilience.*
Scutellaria Baicalensis Root ExtractA traditional botanical extract included to support a calm, balanced scalp environment.*
Soybean and Wheat Germ ExtractNatural conditioning extracts included to help nourish the scalp and support a healthy-looking hair appearance. Both are allergens for some people, which is why they are named at the top of this page rather than only in the ingredient list.*
How To Use It
ApplicationApply four to six drops to a clean, dry scalp nightly. Massage gently for one to two minutes. Lightweight and non-greasy. For external use only. Avoid contact with eyes. Net 1 fl oz (30ml).
How long a bottle lastsMost people get well over three months from one 1 fl oz (30ml) bottle at four to six drops nightly, though it depends how much you use per night. Choose a delivery interval that matches how you actually use it rather than defaulting to monthly.
The honest timelineHair responds on a cycle measured in months, not weeks. What you shed today was decided months ago, which is why shedding tends to surface two to three months after rapid weight loss begins. Take a photo when you start, and judge at month six rather than month one.

Common Questions
Does Ozempic cause hair loss?Hair shedding is a commonly reported experience during rapid weight loss, including with GLP-1 medications. It's driven by the physiological and nutritional stress of rapid body change, and typically appears a few months after the shift begins rather than right away, which is why many people don't immediately connect it to their medication.*
How long does Ozempic hair loss last?Shedding linked to rapid weight loss typically begins two to three months after the change starts and in acute cases tends to resolve within three to six months, though individual timelines vary.*
When should I start using it?Earlier than feels necessary. Because shedding lags the weight loss that causes it by two to three months, by the time you first notice extra hair in the brush the process is already underway.*
What does the research on rosemary and hair actually show?One six-month randomized trial in 100 people with androgenetic alopecia compared rosemary oil with minoxidil 2%. Both groups gained hair count from their own baseline and neither outperformed the other. There was no placebo arm, so that improvement cannot be confidently attributed to either agent, and the population was not people shedding during weight loss. Note also that the published trial used rosemary oil, while this formula uses rosemary extract.*
What ingredients are in TAKE Regrowth?Five cosmetic peptides, in label order: sh-Polypeptide-11 (aFGF), sh-Polypeptide-1 (bFGF), sh-Oligopeptide-2 (IGF-1), sh-Oligopeptide-10 (CCL2) and sh-Polypeptide-9 (VEGF). Alongside them: rosemary, saw palmetto, eucalyptus, arginine, Scutellaria baicalensis root extract, and soybean and wheat germ extracts. The full ingredient list is published above. Regrowth does not contain EGF or KGF; earlier versions of this page said it did, and that was incorrect.*
Does TAKE Regrowth contain allergens?Yes. The formula contains soybean germ extract and wheat germ extract. If you have a soy or wheat allergy, or you avoid topical wheat protein, this is worth knowing before you order.*
How long does one bottle last?Most people get well over three months from one 1 fl oz (30ml) bottle at four to six drops nightly, though it depends how much you use per night. Choose a delivery interval that matches how you actually use it rather than defaulting to monthly.*
