A weightless leave-in treatment with silk proteins that its listing says suits straight, wavy, curly, fine or textured hair and goes on wet or dry hair. - **The leave-in Byrdie names as its drugstore pick:** It's A 10 Miracle Leave-In Conditioner Spray. A leave-in spray whose listing says it eliminates frizz, detangles and adds shine, named by Byrdie as its best drugstore leave-in. Our top pick is the **[Marc Anthony Grow Long Leave-In Conditioner Spray](https://twelvetabs.com/reviews/best-drugstore-leave-in-conditioners/#pick-1)**, a detangling spray for wet or damp hair that its listing says suits men, women and all hair types. We read the 120 Amazon search cards Chrome rendered for “leave in conditioner”, 60 on each of two pages, set aside sponsored cards, salon-priced leave-ins, masks, kids' sprays and listings that share one review total with another product, and compared 10 product pages on what their own listings say. Only three leave-ins from drugstore lines made it through. The [BioSilk Silk Therapy Original](https://twelvetabs.com/reviews/best-drugstore-leave-in-conditioners/#pick-2) is a silk-protein leave-in treatment for all hair types, and the [It's A 10 Miracle Leave-In Conditioner Spray](https://twelvetabs.com/reviews/best-drugstore-leave-in-conditioners/#pick-3) is the one Byrdie calls its best drugstore leave-in. ## How to choose a drugstore leave-in conditioner "Drugstore" here means a leave-in conditioner from a mass-market line, priced like a drugstore product rather than a salon one. We left out salon-priced leave-ins, hair masks and multi-use lotions, and we kept only products sold as a leave-in for the hair. **Hair type and weight.** Byrdie's stylist says that if your hair is on the finer side, a lightweight yet hydrating leave-in will not weigh it down, and that coarse, thick or curly hair can take something richer, such as a milkier leave-in with some thickness. Its top tip is that lighter formulas typically come as sprays and thicker ones as creams or lotions. The [Marc Anthony Grow Long Spray](https://twelvetabs.com/reviews/best-drugstore-leave-in-conditioners/#pick-1) and the [It's A 10 Miracle Leave-In Spray](https://twelvetabs.com/reviews/best-drugstore-leave-in-conditioners/#pick-3) are sprays, and the [BioSilk Silk Therapy Original](https://twelvetabs.com/reviews/best-drugstore-leave-in-conditioners/#pick-2) is a treatment its listing calls weightless. **Ingredients.** Byrdie's stylists look for oils such as almond, coconut, jojoba or argan, and for humectants such as glycerin, and one stylist suggests steering clear of heavy silicones and waxes that can weigh hair down over time. The picks' listings name silk proteins (BioSilk), biotin, caffeine and ginseng (Marc Anthony) and aloe vera, vitamin C and extracts of linseed and sunflower seed (It's A 10). **How often and how.** Byrdie says a leave-in can go on daily, but you may want to alternate or skip days, and that fine or thin hair that builds up product can use it once a week. For sprays it advises misting from roots to ends but avoiding the scalp, and for creams, emulsifying them in your hands and working them through from the ends. **Price class.** Byrdie describes It's A 10 as a leave-in that performs like a high-end product but sits in the drugstore aisle. The salon-priced leave-ins we saw on Amazon are in their own guides or are left out below. ## Our picks in detail ### 1. Marc Anthony Grow Long Leave-In Conditioner Spray: best for a detangling spray for all hair types **Why it made the list** - Its listing calls it a multitasking detangler spray to use on wet or damp hair, roots to ends, combed through. - The listing names biotin, caffeine and ginseng and says it tames flyaways. - The listing says it suits men, women and all hair types and is free of sulfates, parabens and phthalates. - Amazon's own summary says a little goes a long way, that it helps with frizz control and makes hair easy to brush and comb, and likes the fragrance. **Drawbacks** - Amazon's own summary is mixed on greasiness, and its aspect list rates spray performance negative. - The page shows one scent, Grow Long, in its variant menu, so check the scent before you buy. **Skip it if** you want a cream or a leave-in with a milky texture for thick or curly hair. ### 2. BioSilk Silk Therapy Original: best for a silk-protein leave-in treatment **Why it made the list** - Its listing calls it a weightless leave-in treatment with silk proteins for straight, wavy, curly, fine or textured hair. - The listing says to use it on wet or dry hair to detangle, condition and add shine, and that it is sulfate-free and paraben-free. - Amazon's own summary says it controls frizz, keeps hair shiny and soft, is non-greasy and lasts a long time. **Drawbacks** - It is made for all hair types rather than one, and Byrdie says fine hair wants a lightweight leave-in while curly hair can take something richer. - The listing text we read has no full ingredient list. **Skip it if** you want a spray or a product that names its ingredients in the listing. ### 3. It's A 10 Miracle Leave-In Conditioner Spray: best for the leave-in Byrdie names as its drugstore pick **Why it made the list** - Its listing says it eliminates frizz, detangles and adds shine, and can be used alone or as a styling product. - The listing names vitamin C, linseed extract, aloe vera and sunflower seed extract. - Amazon's own summary calls out silky softness, detangling for fine hair, frizz control and shine. - Byrdie names this leave-in its best drugstore pick, and InStyle names it for wavy hair. **Drawbacks** - The page we read shows the 10 oz two-pack, so a single bottle is a different listing. - A 1-star snippet reports a package that burst and leaked in delivery. **Skip it if** you want a single bottle or a leave-in made for thick curls. ## What we left out, and why We read 120 search cards, found 103 different products, read the pages of 10 and kept 3. Only three of the ten pages we read met the guide's definition. - **Garnier Fructis Sleek & Shine Leave-In Conditioner Cream.** The same cream is sold under two Garnier listings, a single and a two-pack, that share one review total, so neither is a pick here. - **Olaplex No.6 Bond Smoother and Redken One United Leave-In Conditioner.** Salon-priced, and each is a pick in our [anti-frizz hair products guide](https://twelvetabs.com/reviews/best-anti-frizz-hair-products/) instead. - **K18 Leave-In Molecular Repair Hair Mask.** A salon-priced mask, not a conditioner. - **SALERM 21 Silk Protein Instant Conditioner.** A salon-line brand priced above the three picks. - **Tea Tree Hair and Body Moisturizer.** A multi-use lotion for hair, body and after-shave, not a dedicated leave-in. - **SO COZY Kids Curl Leave-In Conditioner.** Made for children's curls. ## Questions people ask ### What does a drugstore leave-in conditioner do? Byrdie says a leave-in can detangle, smooth frizz and hydrate, and that most are meant to be worn rather than rinsed out. The picks here are sprays and a treatment from drugstore-aisle lines. ### How do you apply a leave-in conditioner? Byrdie says to start with clean, towel-dried hair. For sprays, mist from roots to ends and avoid the scalp, and for creams, emulsify them in your hands and work them through, starting at the ends and stopping about an inch from the roots. ### Can you use a leave-in conditioner every day? Byrdie's stylist says you can, but you might alternate or skip days, because moisturizing ingredients can build up and leave hair looking greasy. For fine or thin hair that builds up product, she suggests once a week. ### How did TwelveTabs choose these drugstore leave-in conditioners?
