Function of Beauty built a following on customized shampoo and conditioner, plus topical booster shots, but it does not sell an oral hair-growth supplement. Personalized cosmetics can leave hair looking healthier, but if your real goal is growth, the question is whether a custom wash does much, or whether a targeted oral supplement is the better spend. Here is how the best Function of Beauty alternatives compare.
Why look for a Function of Beauty alternative?
The usual reasons are cost over time and wanting something that targets growth directly. Custom shampoo addresses feel and appearance at the surface, while growth is driven by what is clinically dosed and taken consistently, which points toward a transparent supplement.
Custom shampoo vs a growth supplement
A personalized wash can improve manageability and shine, but the follicle responds to nutrition and proven actives over time. That is why, for thinning, we compare the options below on hero ingredient, dose, and transparency rather than on customization. For what actually matters in a cleanser, see our shampoo for hair loss ingredient guide.

1. HAIRLOVE Growth Complex: best overall value
This is the piece Function of Beauty does not actually sell: a dedicated oral growth supplement. Growth Complex is built for exactly that job, with Cynatine HNS keratin and a fully listed nutrient blend in a two-capsule daily dose, backed by a one-year money-back guarantee. Pair it with a cleanser you like and you have covered both the surface and the follicle. See Growth Complex or a first-order discount code, and our best scalp serum for hair growth guide for a topical companion.
2. Nutrafol: best known brand
If brand familiarity matters most to you, Nutrafol is the household name, sold through dermatology offices and major retailers, though its proprietary blend keeps the exact doses behind a curtain. See our best Nutrafol alternatives guide for the full comparison.
3. Viviscal: best budget pick
For the lowest sticker price, Viviscal is the usual pick, though its marine complex is fish-derived, which rules it out for some allergies and diets. See Viviscal side effects.
4. Vegamour: best topical alternative
Vegamour's GRO serum is the topical, plant-forward option for people who prefer not to add a pill, and it pairs with an oral supplement since the two act differently.
How to choose
