Protecting Hair From Sun & Hard Water

Your hair feels different in Pasadena because of the unique combination of intense year-round UV exposure and very hard water (12.9 to 14.3 grains per gallon) that breaks down protein structure and creates mineral buildup. The constant Southern California sun literally breaks down the protein fibers in your hair, creating free radicals that cause oxidation and weaken strands, while the dissolved calcium and magnesium in our water coat each strand with a dulling film that prevents moisture and color from penetrating. The solution is a targeted defense plan: daily UV protection, weekly clarifying to remove mineral buildup, and heat protection to prevent further damage.

One of the most common things I hear in my chair at Bokaos Aveda is, "Hasblady, I just don't get it. My hair feels dry and looks dull, but I haven't changed a thing!" My first question is always, "How long have you lived in Pasadena?" In this guide, you'll discover how Pasadena's environment affects your hair differently than other places, the science behind sun and hard water damage, and the simple defense plan that protects your hair while living here.

It's a beautiful place to live, with our sunny days and gorgeous views of the San Gabriel Mountains. But that same environment we love can be incredibly tough on our hair, and if you've been feeling like you're in a constant battle with frizz, faded color, or brittle strands, you're not imagining it.

That SoCal Sun Is Doing More Than You Think

We all know to put on sunscreen before a walk through Old Pasadena or a day at The Huntington Gardens, but most of us forget our hair is just as exposed. That relentless sun isn't just lightening your color; it's actively breaking down the structure of your hair.

The Science Behind Sun-Damaged Hair

Think of your hair strand as a strong rope made of protein fibers. UV rays act like tiny scissors, slowly snipping away at those proteins, especially one called tryptophan, which is essential for strength. This process creates free radicals that cause oxidation, leading to weaker, more porous hair that can't hold onto moisture or color.

Honey moved to Pasadena from Seattle last February, and within three months, she noticed a dramatic change in her hair. It felt rougher, looked duller, and her natural brown color had developed brassy, orange-toned ends. She came to me in May frustrated and confused because she hadn't changed her hair routine at all.

During our consultation, my first question was, "How long have you lived in Pasadena?" When she said three months, I explained that Seattle gets about 152 sunny days per year while Pasadena gets 284. Her hair had gone from minimal UV exposure to constant sun damage, and it was showing. The UV rays had literally weathered down her hair's protein structure, compromising its natural defenses.

I recommended she start using Aveda's Sun Care Protective Hair Veil every morning before leaving the house, which contains naturally derived UVA/UVB inhibitors from wintergreen and cinnamon bark oils. She was skeptical that a simple spray could make a difference, but agreed to try it. Three months later, in August, she came back for a trim and her hair looked completely different: smoother, shinier, with no new brassy ends developing.

"I didn't realize how much the sun was damaging my hair until I started protecting it," she told me. "Now I don't leave the house without spraying it on, just like my face sunscreen." She's been in Pasadena for a year now, and her hair is healthier than when she first moved here.

The Hard Truth About Pasadena's Water

Now let's talk about what's happening inside your home. The other major factor is our water. According to local water quality reports from Pasadena Water and Power, our water is officially classified as "very hard," with an average of 12.9 to 14.3 grains per gallon (GPG).

Anything over 10 GPG is considered very hard, so we're well into that territory. That means our water is full of dissolved minerals like calcium and magnesium that build up on each strand, creating a dulling film. Imagine trying to put lotion on your hands while wearing gloves; that's what it's like for your conditioner trying to penetrate a hair shaft coated in mineral buildup.

Marceline came to me from Altadena last June complaining that her beautiful blonde balayage had turned dull and brassy within weeks of getting it done. She'd invested in the color and was devastated that it looked so faded so quickly. During our consultation, I asked about her water at home, and she mentioned she has city water.

I explained that Pasadena's very hard water (12.9 to 14.3 GPG) was likely coating her freshly lightened hair with minerals, which was preventing her purple shampoo and toner from penetrating properly and also accelerating the brassy oxidation. The mineral buildup was literally creating a barrier between her hair and the products meant to keep it beautiful. I recommended we do an in-salon botanical treatment to remove the buildup and reset her hair, then start her on a weekly clarifying routine at home.

We did the treatment, and when I rinsed her hair, the water had a slight cloudy tint as the minerals released. After I toned her, her blonde looked bright and cool again. I sent her home with Lakme Scalp Care Purify Shampoo to use once a week.

She came back eight weeks later for a gloss refresh, and her blonde had stayed beautifully bright with minimal brassiness. "I've been doing the weekly clarifying like you said, and it's made such a difference," she told me. "My hair feels cleaner, and my purple shampoo actually works now." She's been maintaining her blonde for nine months with this routine, and it stays vibrant between appointments.

Your Simple Pasadena Hair Defense Plan

Protecting your hair doesn't have to be complicated. It's about incorporating a few smart, targeted steps into your routine. Here is the simple plan I give to people at Bokaos Aveda.

Once a Week, Clarify: Use a purifying shampoo to gently remove the mineral buildup from our Pasadena water. This gives your hair a clean slate so your conditioners can actually work.

Every Morning, Shield: Before you head out, spritz a UV protectant mist through your dry hair, focusing on the mid-lengths and ends. This is your daily armor against the sun.

Every Time You Heat Style, Protect: Never let a hot tool touch your hair without a thermal protectant. Heat protection guards against damage and conditions at the same time.

Jean came to me from La Cañada Flintridge last September with severely damaged hair. She heat-styled every day for work, spent time outdoors hiking on weekends, and lived in an area with very hard water. Her hair was dry, brittle, and breaking off at the ends. She'd tried deep conditioning treatments, but nothing seemed to help.

During our consultation, I explained that her hair was being attacked from three angles: UV damage from outdoor time, mineral buildup from hard water, and heat damage from daily styling without protection. We needed a comprehensive defense plan. I set her up with the three-step routine: weekly clarifying with Rosemary Mint Purifying, daily UV protection with Sun Care Veil, and Aveda's Heat Relief Thermal Protector before every styling session.

She committed to the routine, and we also did a professional strengthening treatment in the salon to repair her existing damage. Three months later, in December, she came back for a trim and her hair transformation was remarkable. It felt smooth and elastic instead of brittle, the breakage had stopped, and she had healthy new growth coming in. "I finally have a routine that actually works," she told me. "My hair hasn't felt this healthy in years."

Common Questions About Hair Care in Pasadena

Can't I just use a drugstore clarifying shampoo for the hard water?

You can, but many drugstore clarifying shampoos use harsh sulfates that can be very stripping, especially on color-treated or naturally dry hair in Pasadena's climate. It's like using dish soap to wash a silk blouse. Aveda's formulas use gentler, plant-derived cleansers and specific chelating agents that target the minerals without removing essential moisture. This is especially important in Pasadena where your hair is already stressed by UV exposure.

Is sun damage a big deal if I don't color my hair?

Absolutely, and we see this constantly at our Pasadena salon. UV damage affects the actual protein structure of your hair, regardless of color treatment. For natural hair, this shows up as dryness, split ends, and a rough, brittle texture over time. Protecting it with a UV spray preserves its natural health and shine, which is especially important with Pasadena's 284 sunny days per year.

My hair feels extra dry. What else can I do?

When hair is stressed by Pasadena's environment, it needs more deep conditioning. At Bokaos Aveda, we often recommend integrating a weekly moisturizing treatment like Aveda's Botanical Repair Intensive Strengthening Masque. It helps repair the bonds in the hair that are broken by sun and heat, rebuilding strength from the inside out. For severely damaged hair, a professional treatment in our Pasadena salon can provide a more intensive reset.

Do I really need to use a heat protectant every time?

Yes, especially in Pasadena where your hair is already compromised by UV and hard water. Heat styling without protection adds another layer of damage to hair that's already stressed. At our Pasadena salon, we recommend Aveda's Heat Relief Thermal Protector, which not only guards against heat but also uses plant-derived ingredients to condition at the same time. This helps counteract the drying effects of our climate.

How quickly will I see results from this defense plan?

At Bokaos Aveda in Pasadena, most people notice a difference within 2-4 weeks of starting the defense plan. Your hair will feel cleaner and lighter after the first clarifying wash, and within a month of daily UV protection and heat defense, you should see less breakage, improved texture, and better color retention. For severely damaged hair, combining the at-home routine with professional treatments accelerates the results.
