can I use this on dry hair as a heat protectant, before straightening or curling?

Thank you for your question! Many R+Co. products, including Park Ave, provide thermal protection, which protects the hair up to 220° F during blow-drying. Currently, as a heat protectant, we offer Smooth & Seal Blow Dry Mist and Hypersonic Heat Styling Mist from the R+Co Bleu line. Both of these products act as heat protection up to 450° F, suitable for use with styling irons.

Does this product have alcohol in

Per their website, no they do not. It’s a vegan/cruelty free product.

Can it just be used on wet hair, then rollers and let hair air dry to help with frizz? Will it keep the curl from the roller?

Thank you for your question! Yes, it can. Hair will be smooth, but with curve and have bounce after removing the rollers. You can also quickly blow dry with a round brush after removing the rollers, depending on your desired end look.

Do you need to use conditioner in addition?

Hello, thank you for your question! R+Co Park Ave Blowout Balm is to be used on freshly washed hair to create a beautiful blowout. We recommend you using your favorite shampoo and conditioner prior, R+Co Bel Air Smoothing Shampoo & Conditioner is a great option.
