The Edit with Miriam Quevedo

Just like our skin, our hair and scalp evolve with the seasons, requiring thoughtful care to stay strong, hydrated, and resilient. From seasonal shedding in spring to winter-induced dryness, understanding how environmental changes impact our hair is key to keeping it healthy year-round. Founder & CEO Miriam Quevedo shares expert insights on how to adapt your haircare rituals, combat frizz, and maintain scalp health using cutting-edge biotechnology and luxurious, high-performance formulas.

1. How does our hair’s needs change with each season?

Our hair and scalp are constantly evolving, responding to environmental changes, temperature fluctuations, and biological processes such as hormonal shifts. These factors can accelerate the aging process of both the hair and the scalp, including the follicles. Additionally, stress, diet, and lifestyle play a significant role in hair health and aging, influencing its strength, shine, and overall vitality.

• Spring is a time of renewal but also a season when many experience increased hair shedding due to reduced melatonin levels. This happens because numerous follicles enter the resting phase (telogen phase). As temperatures rise and daylight hours extend, hormonal adjustments occur, potentially affecting the hair cycle. Changes in diet, allergy season, and inflammation triggered by the seasonal transition can impact hair quality. This is the time to focus on reinforcing hair growth and strengthening follicles to prevent excessive shedding. Repairing winter damage and protecting against increased UV exposure is crucial. Oxygenation is also key for a healthy scalp and optimal nutrient absorption. Incorporating a scalp concentrate, such as our Black Baccara Hair Multiplying Scalp Concentrate + Pre-Treatment Exfoliator, enriched with Fresh Rose Stem Cells and Hair Growth Factors, can help support stronger, healthier hair. For deep exfoliation and detox, the Black Baccara Hair Multiplying Cellular Breathing Scrub Scalp Mask is an excellent choice, paired with a mask tailored to your hair’s specific needs—whether for damaged or extremely damaged hair.

• Summer presents challenges like intense sun exposure, humidity, chlorine, and saltwater, which can cause dehydration, breakage, and oxidative stress. Our priority should be deep hydration, antioxidant protection, and fortifying the hair to minimize post-summer shedding. The scalp must also be protected—remember, this is where the follicles are supported. Inflammation, redness, and sensitivity can negatively impact scalp health. Beautiful hair requires self-care and self-love. Incorporating a detox and purifying shampoo in your double cleansing routine, such as our Extreme Caviar Purifying Charcoal Shampoo, followed by the Platinum & Diamonds Volume Shampoo will help restore shine while providing superior volume from the roots and regulating sebaceous glands. The Black Baccara Collection, rich in adaptogens, is key to maintaining hydration and strength. Our mission in summer is to keep hair cuticles soft, smooth, and nourished for bouncy, radiant hair all season long.

• Fall is the season to repair summer damage, calm scalp sensitivity caused by UV exposure, and address seasonal hair shedding. Hydration, regeneration, and essential nutrients are crucial to fortifying the hair before winter. What’s good for our skin is good for our hair and scalp, making this one of the most important seasons for hair care. This is the perfect time to focus on rejuvenating your scalp and hair with scrubs and masks at home.

• Winter demands protection against extreme temperatures, dryness, and scalp dehydration. This is the ideal time for deeply nourishing and rejuvenating treatments to restore lost vitality and reinforce the hair’s natural barrier. Cold weather affects the entire body, including our muscles. Deep scalp massages are essential to increase microcirculation, release tension, and maintain healthy, shiny, and bouncy hair.

Understanding these seasonal shifts allows us to anticipate our hair’s needs and provide targeted care to maintain its health and beauty year-round.

 

2. How can we prevent seasonal frizz, especially in humid months?

Frizz occurs when the hair’s cuticle is lifted or damaged, allowing excess moisture to enter the hair fiber and causing it to swell. This effect is intensified in humid environments, especially for damaged or porous hair, leading to dryness, lack of definition, and unwanted volume. As we age, frizz can become more prominent due to the degradation of protein bonds within the hair structure. UV rays are particularly harmful, weakening these bonds and leading to reduced strength, elasticity, and hydration.

However, preventing frizz isn’t just about managing humidity—it’s about strengthening, hydrating, and sealing the hair from within.

Several factors can worsen frizz, including using the wrong products, exposure to heat, and even brushing with metal combs that damage the hair structure.

My top tips for frizz control:

1. Deep hydration is essential—use highly potent nourishing treatments to prevent cuticle breakage and enhance shine. I love using deeply nourishing masks on wet and on dry hair.
2. Transform dull hair by smoothing the cuticle for a silky, bouncy finish.
3. Repair damaged hair to reinforce its structure and protect against external aggressors.
4. Exfoliate once a week to ensure the hair and scalp are clean and can absorb moisture effectively.
5. Use UV shields and heat protectants to prevent dehydration caused by styling tools and sun exposure.
6. Switch to wooden combs to avoid breakage and reduce static.
7. Be gentle when drying—never rub your hair with a towel; instead, gently squeeze out excess water with our Deluxe Hair Turban to prevent frizz and breakage hair turban.

At Miriam Quevedo, we harness advanced biotechnology to combat frizz at the source. For example, our Black Baccara Hair Multiplying Leave-In Conditioner, powered by Multi-Bond Filler, Vegan Keratin, and Vitamin C Ester, works at a molecular level to rebuild and smooth the cuticle while providing antioxidant protection. Additionally, our Black Baccara Hair Repairing & Multiplying Serum enhances shine, controls frizz, and protects against humidity—keeping your style flawless in any climate.

3. We’re really leaning into scalp health in 2025. How can we keep our scalp balanced when dealing with seasonal weather changes?

I have always believed that scalp health is the foundation of beautiful, healthy, and resilient hair. As the seasons change, so do the needs of our scalp, requiring tailored care to maintain balance and prevent seasonal concerns such as dryness, oiliness, or sensitivity.

Just as we invest in skincare to combat aging, our hair and scalp deserve the same attention, high potent ingredients, and advanced biotechnology. Hair longevity begins at the root, and understanding the impact of modern lifestyle factors—such as chemical treatments, heat styling, and environmental stressors—is key to preserving youthful, vibrant hair.

During winter, colder temperatures slow sebaceous gland activity, leading to dryness, dehydration, and even flaking. Additionally, prolonged hat-wearing creates a microenvironment that traps heat and humidity, resulting in excess oil production and buildup. To combat this, gentle exfoliation, oxygenation, and deep nourishment are essential.

Spring marks a transition to warmer weather, often triggering seasonal hair shedding. This is the perfect time to reinforce scalp health with vitamin-infused treatments. Exfoliation remains crucial to oxygenate the scalp and prepare it for summer.

In summer, increased sun exposure, heat, and humidity can lead to dehydration, inflammation, and oxidative stress. To protect the scalp, we focus on antioxidants, hydration, and shielding it from environmental aggressors.

Fall is all about repair and recovery. Post-summer inflammation and damage can accelerate seasonal hair shedding, so incorporating strengthening treatments and deep hydration is vital.

Regardless of the season, a healthy scalp is the key to strong, youthful hair. By adapting our routines and using targeted, high-performance formulas, we can ensure our scalp remains in perfect harmony year-round.

4. How often should we be washing our hair, and how does that change based on hair type, season, or lifestyle?

There is no universal rule, as every scalp and hair type is unique. The key is understanding your hair’s needs and choosing the right shampoo—not just focusing on frequency.

If you have fine hair or an oily scalp, you may feel the need to wash daily, which is perfectly fine—as long as you’re using a gentle, sulfate-free shampoo that respects your scalp barrier. Those with thicker, more porous hair or a dry scalp may not need to wash as often, but should focus on deep hydration and nourishment.

Lifestyle also plays a major role. If you use styling products daily or live in a polluted environment, washing your hair more frequently can help remove buildup and impurities. In summer, it’s essential to cleanse your hair after exposure to saltwater or chlorine to prevent dehydration and damage.

The real question is not how often you should wash your hair, but how well. The key is a double cleansing ritual, using high-performance formulas that cleanse while treating the scalp. At Miriam Quevedo, our shampoos are not just cleansers—they are treatments, meaning they go beyond cleansing to deliver targeted results. They are formulated with smart sulfate-free cleansing agents derived from amino acids to purify without stripping the natural oils on the scalp.

Our philosophy: Less is more. Our highly concentrated shampoos require only a small amount, yet deliver maximum active ingredients to achieve transformative results. With the right formulas and a mindful cleansing routine, we can achieve bouncy, healthy hair that begins with a perfectly balanced scalp.

At Miriam Quevedo, we fuse precious ingredients with the most advanced biotechnology to create high-performance, anti-aging formulas. Our approach is to break down active ingredients into various molecular weights to ensure deep penetration at multiple levels, delivering truly transformative results.

6. What recent innovations have you seen in the world of haircare, and how do they influence your approach to formulating products? 

The world of haircare is evolving at an exciting pace, with biotechnology leading the way. We can now mimic and enhance natural biological processes to create next-generation, highly effective treatments for both scalp and hair longevity.

Our newest formulations incorporate a fusion of biotech peptides, stem cell technology, and encapsulated actives to optimize scalp health and extend the hair’s natural life cycle.

Another key innovation is targeting the scalp microbiome. A balanced microbiome is crucial for strong, healthy hair, which is why we incorporate prebiotics and probiotics into our products to nourish and protect this delicate ecosystem.
