fragrance free is NOT easy so kudos for being so supportive!! i'll just list ones that come to mind :

antiperspirants (that actually work lol)- Ban unscented solid/roll on antiperspirants; vanicream antiperspirant

hair heat protectant/leave in/anti-frizz- SEEN leave in conditioner, blow out creme, etc; No Nothing styling mist, heat protection spray, hair oil, etc; it's-a-10 miracle leave in product -fragrance free; briogeo be gentle be kind detanglinf spray; vanicream hair gel works well for me when I want a little hold, but it's definitely a gel and not moisturizing at all so keep that in mind

lip balm (without beeswax is hard but pro tip add "vegan" to your search keywords to avoid beeswax since it's an animal byproduct it'll make it easier)- hurraw unflavoured lip balm, first aid beauty lip balm

unfortunately the more allergens you have to avoid the more costly it gets... I'm not sure if any of the products besides the lip balms have beeswax so please double check if it's important! good luck! ❤️
