Incredible: I forgot that I even put this sunscreen on
This product is worth every penny! It spreads easily, completely absorbs into my skin, and dries down invisible. It’s not tacky, greasy, or chalky, and did not transfer onto clothing.
I have very sensitive skin and break out in hives from chemical sunscreens. No reaction from Mayday! Most mineral zinc-based products go on thick like white paint. I’ve tried so many brands that claimed to have sheer mineral formulas, but applied like spackle. Mayday is the best sunscreen formula I’ve found for day-to-day wear.
I was optimistic about it based on the slightly runny consistency I saw in the ads, and it did not disappoint. I haven’t tried it on my face yet, but I don’t think it will clog pores or interfere with makeup based on how lightweight it is. If you have very dry skin, you might want to apply a moisturizer first. I also haven’t worn it while swimming yet, but I’m relieved that it’s convenient to reapply and safe for the oceans.
I’m hesitant to rave about it because I don’t want this sunscreen to sell out or the price to skyrocket. But I also want people to be protected from the sun and, of course, for this brand to be successful. So order two bottles and tell a few of your friends, but don’t tell the whole world, because some of us burn easily and need the good stuff!
We just got our first email from my son's preschool about a lice outbreak and it felt great to know the headache, missed work, etc we had avoided by using Mayday, kids love the scent and the conditioner leaves their hair feeling really soft too!
I have been searching high and low for a mineral based sunscreen that didn't feel sticky or leave a white residue. I have tried EVERYTHING and nothing worked. Mayday finally did it!
My entire family had lice and we tried a bunch of stuff and Mayday was by far the best. First off, it worked. Second, I liked that it could be used like regular shampoo and conditioner. And lastly, it didn’t contain arm of the harmful ingredients found in the generic brands. An added bonus was the conditioner- I almost rarely use conditioner but really like the way this one feels. Overall, great shampoo that I can use every week and that also happens to kill and prevent lice.
Mayday sun tan lotion is light & doesn't leave my skin feeling sticky or slimy like some others. Its natural ingredients give me peace of mind about putting in on my skin and knowing that I'll be protected.
It's the worst when you use bug spray that smells less than ideal, right? But you're willing to sacrifice as long as it works. Then, turns out it doesn't work all that well. That is not the case with Mayday's product- it smells light and refreshing and it works so well. I'll always have some on hand!
So happy to have this in our arsenal. The kiddos get sick from school often enough. We've had a few lice scares this year, so the peace of mind that Mayday provides is invaluable. So, so happy to have found this shampoo and conditioner. We love including it in the rhythm of tubby time.
Great fragrance out of the bottle and leaves our kiddos smelling super fresh. Love that it’s an all-natural formula that lets us proactively guard against lice as opposed to scrambling for a solution after the fact.
Mayday lice shampoo and conditioner are genius. Our kids use them just like their old shampoo and conditioner. My 6 year old really likes the smell. The lice defense gives us so much peace of mind given that there have been lice outbreaks at our school this year.
Got an email from the school nurse about lice at school. Looked for something that my daughters wouldn’t fight. I’m so glad we found Mayday shampoo & conditioner. It gives us peace of mind, smells great and the girls are happy to use it. It’s definitely going in the trunk for camp this summer.
I sent my son to camp last year and totally underestimated what we’d need. This time, I’m feeling way more prepared. The shampoo, conditioner, sunscreen, and bug spray are all in one place, and I actually feel good about the ingredients. No weird chemicals, and it all smells great. It’s just one less thing to stress about.
The emotional roller coaster is real. Where do we turn? Who do we trust? Finding a straight answer can feel hopeless. That’s why we decided to introduce clarity to anxious experiences.
Choose our Daily Defense Shampoo and Daily Defense Conditioner for Lice Prevention. Use it any time you or your kids are at risk of a lice infestation, such as at school, summer camp, sports seasons etc…
If you already have an active infestation that you need to crush, you can use our Shampoo to kill lice and their eggs! We recommend using it for 14 days straight to be extra safe.
Can Mayday products be used for lice treatment?
Although Mayday Lice Prevention Shampoo is designed to kill stray lice before a full infestation occurs, bench studies show it can also be a safe and effective treatment when used properly.
To use as a treatment: Apply a generous amount of shampoo to the crown of the head and massage thoroughly into the hair. Add more as needed to fully saturate all strands. Leave on for 3 minutes, then rinse completely. Follow with Mayday Lice Fighting Conditioner.
Once all product is rinsed out, detangle the hair and use a lice comb to remove lice and nits. For best results, repeat every 24 to 48 hours over a 3-week period.
*For young children, we strongly recommend that an adult apply the shampoo to ensure effective use.
