Chaos Fragrances / Head to head
Rehab vs. Althaïr
Which should you buy?
Rehab is our starting pick when lavender, woods and musk are what you want. Althaïr goes first when vanilla, spice and praline are the attraction. These are different reasons to buy a luxury fragrance, so begin with your taste before comparing bottle sizes. The featured Jomashop links select Rehab 90 ml Extrait de Parfum and Althaïr 75 ml Eau de Parfum.
Sample Rehab first for an aromatic woody addition to your regular rotation. Sample Althaïr first for the sweet vanilla preference. If both appeal, compare them with what you already wear: the better purchase is the one that earns a useful role. Rehab’s featured bottle contains 20% more fragrance, while Althaïr offers less volume to work through.

Rehab
- You enjoy aromatic woody fragrances
- You want a candidate for regular use
- You already own a sweet evening favorite
Althaïr

The differences that matter.

Two different reasons to reach for a bottle
Initio describes Rehab with bergamot, black pepper and lavender over sandalwood and musk; its main notes also include cedarwood, patchouli and Hedione. Parfums de Marly pairs Althaïr’s citrus and elemi with orange blossom and spices, then bourbon vanilla, guaiac wood and praline. Those official profiles inform our editorial split: Rehab for the aromatic woody interest, Althaïr for the vanilla-centered brief.
Rehab
Put Rehab first when you want this scent direction in a regular rotation. We would also begin here if you already have a sweet evening favorite and want to explore another idea. Try it during an ordinary day and compare it with the bottle you usually choose for those plans.
The tradeoff An Extrait label is a poor reason to stretch the budget if the other fragrance is the one you prefer. The 90 ml format offers more volume, but it should earn that space through repeated use. Give the sample enough time to move beyond its first impression.

Althaïr
Start with Althaïr when this is the scent idea you want from the purchase. We would sample it for dinners, relaxed evenings and cool-weather weekends built around that preference. Compare it with your existing choice for those plans before deciding whether you want another full bottle.
The tradeoff The featured 75 ml format may suit occasional wear, but a smaller bottle does not automatically mean better value. If you are unsure about the dessert-like theme, spend time with a sample first. Choose original Althaïr if that is the fragrance you tried; Althaïr Exclusif is separate.

Where will you wear it?
Use these as starting points. Your preferences and application matter most.
A fragrance for regular use
Start with Rehab for the woody preferenceUse an ordinary day as the sample trial. Follow your usual routine and ask whether you would choose it again next week. A bottle intended for frequent wear should appeal beyond a special occasion or a memorable first impression.
Dinners and evening plans
Start with Althaïr for the vanilla ideaThis is our first sample choice when that style is the reason for the purchase. Follow it through the evening and compare it with your current favorite for similar plans. If Rehab is the one you enjoy more, it can fill this role too.
A cool-weather weekend away
Choose the sample you would packTry each on comparable days before committing to a full bottle. Consider the meals, walks and casual plans you actually make. The fragrance you want to revisit earns more weight than a generic seasonal label.
Adding to an established collection
Find a role you want to fillList what you already wear for work, casual plans and evenings. Compare the candidate with its nearest alternative in your collection. If both samples appeal equally, the smaller Althaïr format may suit occasional use, while Rehab’s extra volume can be useful for regular wear.
The concentration label does not choose the winner
Rehab is labeled Extrait de Parfum and Althaïr Eau de Parfum. That does not establish which will last longer or project more on you. Try similar applications on separate days and check how each fits your plans from beginning to end. Notice whether you still enjoy the scent and want to wear it again, rather than judging only the opening.
Found your signature?
Buy Rehab when its woody direction is the one you want to wear more often. Buy Althaïr when the vanilla-and-praline idea is what drew you in. If both samples work, compare each with your nearest existing favorite and decide which adds a choice you will use. Then let the selected size and final total help settle the purchase.

See fragrance & retailer options →Compare the value. The featured Rehab bottle is 90 ml and Althaïr is 75 ml: Rehab contains 15 ml more, or 20% more volume. Compare final totals after shipping, tax and applicable coupon terms, then divide Rehab’s total by 90 and Althaïr’s by 75 for cost per ml. At equal totals, Rehab would have the lower unit cost. Choose your preferred fragrance first; a smaller bottle can make sense in a large rotation. Recalculate if you change sizes, and compare standard bottles separately from testers, samples, open-box offers and gift sets.
Still deciding?
Should I buy Initio Rehab or Althaïr?
Our starting recommendation is Rehab for the aromatic woody preference and Althaïr for someone seeking a sweet vanilla idea. Try your preferred direction first, then compare the role each would fill and the final totals for the selected bottles.
Are Rehab and Althaïr similar?
Both official profiles include bergamot and woody notes, but they give different reasons to consider a purchase. We put Rehab first for the lavender-and-woods interest and Althaïr first for the vanilla-and-praline theme. Compare samples before deciding that either replaces the other.
Is Rehab an Extrait de Parfum or an Eau de Parfum?
Initio identifies Rehab as Extrait de Parfum, and the featured Jomashop product title uses that concentration. The listing’s URL contains an EDP abbreviation, so use the full product title and selected format to identify the bottle. This guide compares Rehab Extrait with Althaïr Eau de Parfum.
Which lasts longer, Rehab or Althaïr?
The Extrait and EDP labels do not establish a universal longevity winner. Compare similar applications on separate days and check each later in your plans. Choose the one you enjoy wearing through those plans rather than assuming its concentration guarantees better performance.
Are the featured Jomashop bottles the same size?
No. Rehab item 3701415900035 is the standard 90 ml / 3 oz Extrait de Parfum spray. Althaïr item 3700578504371 is the standard 75 ml / 2.5 oz Eau de Parfum spray. Rehab contains 20% more volume. Divide final totals by 90 and 75 respectively to compare cost per ml.
Does this comparison include Althaïr Exclusif?
No. The featured Parfums de Marly fragrance is original Althaïr Eau de Parfum. Althaïr Exclusif is a separate fragrance. Match the full name to the version you sampled, then confirm the size and condition of the selected offer.
