Shedding but told your blood work is normal? Trichologist Clare Devereux explains the five tests your hair actually needs, what the numbers should really be, and why "in range"…
Understanding shedding vs breakage is the first step to treating your hair correctly. This simple 30-second check tells you which one you are dealing with.
Washing hair when shedding is widely misunderstood. Here's the biology — and what actually matters for your scalp during a shed.

You’ve noticed your hair feeling thinner and less full over the past six months or so — particularly around your parting and when you tie it back. You mentioned that you’ve reduced washing to once a week after reading that frequent washing causes hair loss, and that you’re blow-drying most mornings on a high setting. Work has been intense, sleep hasn’t been great, and you’re wondering whether all of this is connected. It makes complete sense that you’re concerned.
What you’re describing is consistent with a pattern we see regularly — and the encouraging thing is that several of the contributing factors are things you can change. There probably isn’t one single cause. It’s more likely a combination of things reinforcing each other, which is actually good news — because addressing even two or three of them tends to produce noticeable improvement.
Scalp environment. Washing once a week may feel gentler, but for most people it allows sebum, product residue, and dead skin cells to accumulate on the scalp. Over time, this can create a congested follicle environment that isn’t ideal for healthy growth. The idea that washing causes hair loss is one of the most persistent myths in hair care — the hairs that come away in the wash were already in their shedding phase. Washing didn’t cause them to fall; it simply collected what was already on its way out.
Heat and breakage. Daily blow-drying on a high heat setting can weaken the hair shaft over time, particularly in the mid-lengths and around the face where hair is finer and more exposed. This creates breakage that can look and feel very similar to thinning — the hair isn’t falling from the root, but it’s snapping shorter, which reduces overall volume and coverage.
Stress and sleep. Both are genuine physiological contributors to hair health, not just things people say. Sustained stress can shift a proportion of follicles into a resting phase earlier than usual, and poor sleep disrupts the repair processes that happen overnight. Research suggests these effects typically show up in the hair 2–3 months after the period of stress — so what you’re seeing now may partly reflect how things were a few months ago.
Life stage. You haven’t mentioned this and it may not be a factor at all, but it’s worth noting that hormonal shifts in our early-to-mid forties can subtly change hair density, texture, and growth rate. This is completely normal and doesn’t mean permanent loss — but it does mean that scalp health and routine become more important, not less.
You mentioned using a supermarket volumising shampoo. Many of these contain harsh sulphates that strip the scalp’s natural oils, triggering the scalp to overproduce sebum in response — which then makes you feel like you need to wash less. It becomes a cycle. Breaking that cycle with a gentler formulation is the single most impactful change you can make.
Moisturising Shampoo — every 2–3 days
Replace your current shampoo with this. Apply to the scalp (not the lengths) and massage gently for 60 seconds before rinsing. The 60-second massage isn’t just about cleansing — it’s about manually stimulating the scalp and ensuring the product reaches the follicle environment. Washing every 2–3 days keeps the scalp clean without stripping it. Your scalp will tell you the ideal frequency — the goal is a scalp that feels calm, clean, and balanced after each wash.
This is COSMOS Natural certified and formulated without the harsh sulphates that are likely contributing to your current scalp imbalance.
Moisturising Conditioner — after every wash, lengths and ends only
After rinsing the shampoo, apply from mid-lengths to ends — keep it away from the scalp. Leave for 1–2 minutes before rinsing thoroughly. This replaces the moisture that washing removes and provides a smoother surface on the hair shaft, which directly reduces the breakage you’re experiencing. Smoother hair also means less snagging when you brush or style, which matters when volume is already reduced.

Rosemary Scalp Oil — 2 evenings per week, before a wash day
Apply 4–6 drops to your parting and the areas where you’ve noticed the most change. Massage lightly for 30 seconds per area and leave on overnight or for at least 20 minutes before washing. Some evidence suggests rosemary oil may support a healthier scalp environment for growth signals — but consistency over weeks matters more than quantity at each application.
If your scalp is sensitive, patch test first — apply a small amount behind your ear and wait 24 hours. Skip the oil entirely if you experience itching, flaking, redness, or irritation.
Keratin Glow Mist — after every wash, on damp hair
Mist lightly through mid-lengths and ends while hair is still damp. This serves two purposes: it provides a light heat-protective layer for when you blow-dry, and it supports the hair you have right now — reducing breakage, adding body, and improving manageability. Less breakage means more visible length and volume, which makes a real difference while your scalp health is recovering.
Adjusting your blow-dry
You don’t need to stop blow-drying — but switch to a medium heat setting and keep the dryer moving rather than holding it in one place. If possible, let your hair air-dry to about 80% and then finish with the dryer. This dramatically reduces heat exposure to the most vulnerable areas. On days when you’re not leaving the house, skip the dryer entirely and let the Keratin Glow Mist do the smoothing work on its own.
Weeks 1–2
Your scalp will adjust to the new wash frequency — it may feel slightly oilier for the first few washes as it recalibrates from the once-a-week cycle. This is normal and settles quickly. What you’ll likely notice first is that your hair feels softer, more hydrated, and easier to manage after washing. The “straw-like” feeling that harsh sulphate shampoos leave behind should start to ease.
Weeks 3–4
By this point, your scalp should feel noticeably calmer and cleaner. You may start to see less hair in the drain and on your pillow — not because the shedding has stopped overnight, but because you’re reducing the breakage component that was making things look worse than they are. This is the first win. Visible regrowth takes longer (typically 2–4 months), but stabilisation and reduced breakage are the foundation everything else is built on.
Signs that your hair may need further investigation
Separately from your routine, there are some signs that suggest a hair or scalp concern may benefit from a deeper clinical assessment or a conversation with your GP. Please reach out to us or your doctor if you notice:
· Sudden patchy hair loss, burning, heavy scaling, or significant redness
· Shedding or thinning that continues beyond 3–4 months with no sign of settling
· Loss of eyebrow or eyelash hair
· A history of thyroid issues, iron deficiency, or autoimmune conditions
· Significant changes in your menstrual cycle or other hormonal symptoms
If you’re concerned about whether hormonal or nutritional factors might be playing a role, a simple blood panel through your GP (including iron, ferritin, thyroid, and vitamin D) can provide useful clarity. We’re happy to advise on what to request if that would help.
