Beauty products: Hair Dye? Sunscreen? Face products/retinol?
I'm far from being done with treatment - waiting on 2nd set of scans (MRI, bilateral mammo) after consulting radiologist saw extra stuff on my original imaging, joy - but I'm trying to build a plan NOW for "after treatment" since I'm a big long-term planner and it calms my anxiety to be able to make little plans for the future post-BC-treatment.
But I have some questions that I haven't found definitive answers for:
Hair Dye? - A couple of studies shows correlation (not causation, but still) between BC risk and permanent hair dye. The MO I had an initial consult with kind of blew me off about this and said "well I dye my hair too", but I'm curious to see what your oncologists have said about this. I have pretty much salt-and-pepper hair now (started greying early in my 30's) so I'm afraid something like henna wouldn't work well on my numerous greys. Is it the PPD / parabens / ammonia that is concerning in permanent hair dye? There's 2 brands of commercial dye that I've seen mentioned as being "safer" -- Goldwell Elumen which I think my local salon carries, and Schwartzkopf Simply Color (box dye) which advertises as "PPD & PTD free" and "Permanent color with 0% ammonia, 0% silicones, and 0% alcohol". Would appreciate any info on either as being safer for BC patients.
Sun screen? Since 2014 I've been using, daily, the french formulation of La Roche Posay Anthelios Ultra lotion & spray which has Mexoryl (not FDA approved in US yet, afaik) UVA blocker. I think it also contains the hormone-disrupting/reef-killing chemicals that have been under discussion. Since getting diagnosed with BC this year, I've been paranoid about anything that might disrupt reproductive hormones since I have ER/PR+ IDC. Am I overworried? I tried switching to Blue Lizard mineral sunscreen but to be frank, it's so crappy compared to the LRP stuff -- hard to apply, ghastly white cast, even harder to wash off/leaves residue. Any good experiences with other brands of mineral (mainly interested in the zinc oxide only versions, without titanium dioxide)? Should I even be worried about using chemical sunscreen vs mineral or is it my post-BC anxiety/paranoia?
Face lotions/serums esp. anti-aging/retinol? I've been using retinol products since my mid 20's (I'm 45) but I have read that anti-oxidants are not encouraged for BC patients because of some studies that show worse cancer outcomes with those who took anti-oxidant supplements. I forgot to ask the oncologist about this during our meeting. Does your oncologist say it's safe to use anti-oxidants on your face? How about retinol, or retinoids like Differin? I'm trying to find a safe, good anti-aging serum or face lotion that won't have anything to possibly contribute to more BC risk. Sorry if that sounds paranoid, but I will admit I'm a control freak and the BC diagnosis has me scrambling to try to find ways to reduce recurrence chance however I can without going full-tilt Quixote and jousting with windmills.
I appreciate your input, thank you.
