Hair & Scalp Serums

Tara's serums are built on the actives with receipts. The density hero is a peptide stack: a biochanin-A and acetyl-tetrapeptide-3 combination raised terminal hair count 8.3% against 8.7% for 3% minoxidil over 24 weeks, with no significant difference between the two arms, in an independent triple-blind trial of 32 people with androgenetic alopecia (Lueangarun & Panchaprateep, J Clin Aesthet Dermatol 2020). Rosemary earned its own head-to-head, matching 2% minoxidil on hair count over six months in a 100-person trial of pattern hair loss (Panahi, Skinmed 2015).

What these serums do not do: red onion is the collection's identity botanical, not its density active. The well-known 87% regrowth figure comes from crude onion juice on alopecia areata, an autoimmune condition, not androgenetic thinning (Sharquie, J Dermatol 2002), and the bulb extract here sits far below that intervention. Density is carried by the peptides, at their studied dose.
