About
What it is.
Custom Conditioner is a rinse-out deep conditioner from Function of Beauty, formulated as part of the brand's build-your-own hair care system. Each batch is mixed to a customized formula rather than sold as a fixed recipe, with liquid consistency and a lightweight texture meant to sit on straight, wavy, curly, or coily hair without weighing it down. It comes in a 16 oz bottle, dye-free unless a color is chosen, and is built around nourishing ingredients aimed at hydration.
It's suited to adults across any hair texture who want a conditioner ready to use straight from the bottle for everyday washing, without needing to layer on separate treatments or hunt through a shelf of texture-specific products.
The verdict
Function of Beauty Custom Conditioner delivers strong shine and scent that customization-focused buyers love, but moisture and breakage outcomes split sharply between users, making it a better bet for those prioritizing fragrance and gloss than those seeking reliable hydration.

Find your situation?
Made for some — wrong for others.
You need a conditioner that works straight from the bottle with no fuss.
Personalization happens once at signup, then it's a standard apply-and-rinse routine; no daily configuration or complexity required.
You want a proven, low-risk conditioner with broad consensus behind it.
6,212 ratings show strong consensus and trust; established DTC brand with mature product; customization adds confidence in fit-to-need.
You want noticeable hair improvement without overspending on premium brands.
Mid-range price with strong 4.4/5 rating and high marks for softness, shine, and efficiency covers core needs well, though cheaper alternatives exist that do most of the job.
You love discovering products with thoughtful design and a passionate community.
Customization and scent are high-rated strengths that appeal to engaged users; solid reviews suggest a following, though not cult-status level.
You demand objectively top-tier performance across every hair concern.
Solid rating and customization strength, but frizz control is weak and hydration only mid—clear quality gaps versus best-in-class conditioners. Consider No. 8 Bond Intense Moisture Mask.
You seek prestige and heritage from an established luxury hair brand.
Function of Beauty is a direct-to-consumer personalization brand, not a heritage luxury house; lacks the prestige positioning premium buyers expect. Consider Regenerating Mask with Prickly Pear Oil.

Frequently asked
What buyers want to know.
What does this conditioner do well?
Buyers rate it highest for product efficiency and hair softness and shine. Long-term owners report needing less product to clean and soften their hair, and they notice visible shine after use. The customizable scent is a strong point—owners often stick with the same fragrance for years.
What's the main issue buyers run into?
Moisture and breakage outcomes split sharply. Some buyers find their hair feels dry and frizzy after use instead of hydrated, with poor detangling and difficulty maintaining texture throughout the day. Others report significant hair loss and breakage. Hydration and moisture delivery rate lowest among buyers at 3.8 out…
Who should buy this conditioner?
It's a better fit for buyers prioritizing fragrance and shine than those seeking reliable hydration. If you care about customization and scent options and don't have significant dryness or breakage concerns, long-term owners report strong satisfaction and the ability to adjust the formula as your hair needs change.
Does customization actually matter with this product?
Buyers who engage with customization love it. Long-term owners report adjusting their formula based on how their hair condition changes—for example, when bleaching and coloring frequently—and say they keep reordering because the personalization works for them.
How does it handle frizz control?
Frizz control rates lowest among all performance categories at 3.2 out of 5. Some buyers report the conditioner actually worsens frizz rather than taming it, so this isn't a strength if frizz is your main concern.
